Installation & Troubleshooting

Answers to common installation queries

Caddie 22 will not start - missing dll


  • Caddie 22 or later


Having installed Caddie 22, on first start an error message is shown:



The Microsoft Visual Studio 2015 C++ redistributables failed to install correctly. This can happen for a number of reasons depending on the operating system:

Windows 7: Windows 7 Service Pack 1 is required before the redistributables can be correctly installed.

Windows 8.1: Windows 8.1 Update KB2919355 must be installed before the redistributables can be correctly installed.

Once the above files have been installed the redistributables should be uninstalled and reinstalled. Doing a repair rather than an uninstall and reinstall is unlikely to fix the issue.



Caddie Backup and Save Stop Working

Applies To

Caddie Professional & Budget


Caddie Professional & Budget stop saving after double clicking a drawing file in Windows Explorer to open it, on some machines.

The following fix rectifies the problem but it can occur again if you double click a file in explorer again. A permanent software fix will be made available, or alternatively the temp folder can be relocated by changing the registry, which also provides a permanent solution.


Description of Errors



To resolve the error when Caddie does not want to save a file nor do a backup when in Professional or Budget mode:


1.       Open up the Registry Editor in Windows

1.1   Click on Start

1.2   Type in Regedit in the search box

1.3   Click on Regedit.exe

2.       Open the directory tree as follow:

2.1   HKEY_CURRENT_USER > Software > Advanced Computer Solutions > (Your Caddie version) > Caddie > SysVars > Env > App > NamedDirs

2.2   Check to see where the TempDir should be (in this case C:\ProgramData\Advanced Computer Solutions\Caddie20 (x64)\temp\)

3.       Check and recreate the missing folder

3.1   Open Explorer

3.2   Browse to the folder as described in your Registry

3.3   If the temp folder does not exist you need to create a folder called temp

4.       This will allow you to save and backup your drawing again.

The Common Folders (Such As Plotstyles) Have Moved From Caddie 16 - Where are They Now?

Applies To

Caddie 16


 Where are the default locations for the various user settings, such as plotstyles, templates and fonts etc.


Prior to Caddie 16 the default common and user, folders and files, such as Plotstyles, Styles, Hatches, Templates etc., where contained within the Caddie installation folder. Over the years the security of the Windows® operating system has been tightened and access to folders within the 'Program Files' folder needs special privileges.

To comply with Microsoft® standards, from Caddie 16 these "User" folders and files have been moved to a more accessible folder within the Windows® environment. Depending with variety of operation system you have will depend where the folders are and what they are called. In order to make accessing these folders easy, Caddie has added a section 'MENU | UTILITIES | BROWSE'. Here you will find two links:

Common Application Files & Folders

These are the ones that every user can access and includeds some or all of the following



Block Libraries

Config Data

Fonts Hatch


Plotstyles Styles

Files (Caddie Defaults)

Arch-SA.ldf (Arch-SA Layer Definition)

Caddie.ks (Keyboard Shortcut)

Caddie.ldf (Caddie Layer Defination)

USCommon.dic (Dictionary)

USMain.dic (Dictionary)

USUser.dic (Dictionary)

User Folders & Files

These are the Files &  folders specific to the current logged in user and includeds the following:

Files (User Specific)
customcommandnames.txt (
userCaddie.ksu (Dictionary)
userCustomizationData.dat (Screen Layout Data
Various Temporary Files
These changes will also make it lot easier when installing future versions of the software, as none of the folders need to be changed.


You can specify the actual folder used using 'SETTINGS | ENVIRONMENTAL SETTINGS | FOLDERS'. This is also a good place to check the folder paths you may have previously set up. 


Virtual PC for running older versions on Win 7 64 BIT

Virtual Machine


How to set up a virtual PC on Windows 7 x64 for Caddie versions older than V16

1. Get the Windows 7 64 BIT update from Microsoft.  Download and install it. (Please not that according to Microsoft, the "Windows Virtual PC" is only supported on Windows 7 Ultimate and Professional)

2. After you have installed the update from Microsoft, you will be able to acces under the Program List

You can click on "Start | All Programs | Windows Virtual PC".



3. After you opened the Virtual PC application, click on "Create virtual Machine" on the top of your window which will be just underneath your Main menu.  Please take note that for this exercise in this article you will need a Windows XP installation disc with a valid license code.



4. On the "Create a virtual machine" window, type a name for you Windows XP installation and choose a location for where your Virtual machine file will be stored. Make sure your XP installation disc is inserted.


5. If it prompts you with a question that the folder doesn't exist and if you want to create it, click on "yes".


6. In this next step, you can allocate the amount of RAM that the Virtual machine will use. This is part of the current RAM (Memory) that your computer is using, so bare in mind that you cannot allocate too much, otherwise there won't be enough memory left for your current Windows 7. If you have 4GB memory installed, I would suggest to allocate 2GB (2048MB) for the XP virtual machine. Then also leave the "Use computer network connections" box ticked if you are on a network, and then you can utilize that network settings to browse to file etc.; Then click on "Next".


7. On this next window, the default setting will be on "Create a dynamically expanding virtual hard disk". This option will use the current hard drive that you choose and install the virtual disk there, and it will us as much space as required, and it will grow (use more space on the drive) when you install more appications on the Virtual Windows XP. In this option you can give your machine its desired name, and also choose where it will be installed (where it will use the hard drive space). After you have done that, click on "Create".


8. In a short while, this will now have created a "Virtual disk" with a .vmcx extension.


9. Right Click on that Virtual machine, and click on "Open".


10. You will see an indication that the Virtual Machine is starting up.


11. The next screen will show a DOS-based screen that will show the files being copied for the Windows installation.


12. In the next screen of the setup, press "Enter" on they keyboard as indicated on the screen.


13. On the next screen, press "F8" on the keyboard.


14. In the next setup screen, you will now see the drive that you selected to install the Virtual machine on, with the amount of free space on it. Select the desired drive and press "Enter" on the keyboard.


15. The next step, select the first option "Format the partition using the NTFS file system (Quick)and press "Enter" on the keyboard.


16. In the next window it will show that it is formatting and following that, it will show the files being copied.


17. After the files are copied successfully, the computer will show that it is going to reboot. Keep in mind it is not the actual computer rebooting, but just the "Virtual Machine"


18. The virtual machine will then boot as it will in a normal computer with windows XP on.


19. After it booted up, the setup will start again, and you will get a window asking for your input as soon as you click inside the window, another window will pop-up explaining that your mouse pointer will be captured inside the Virtual machine, and to "release" it again (meaning that you can use your mouse outside the virtual machine), you have to press Ctrl+Alt+Left Arrow together on the keyboard. As showing in the picture below, point number 1 is to click on the "Customize" button.


20. Click on the arrow next to English (United states), and change it to English (South Africa) or to the country that you are situated in. This is for the currency settings.


21. Then choose your country/location, and then click "OK".


22. On the "Regional and Language options" step, click on "Next".


23. On the "Personalize your Software" step, type in a desired Name and organization details, and then click on "Next".


24. On the "Your Product Key", enter the product licence key that you have for your XP installation,and then press "Next".


25. In the "Computer name and Administrator password" step, type in the name that you would want for the Virtual PC, leave the Administrator password blank, and click on "Next".


26. On the "Date and Time Settings" step, make sure your settings are correct, and click on "Next".


27. On the "Networking Settings" step, select the "Typical Settings" option, and click on "Next".


28. On the "Workgroup and Computer Domain" step, select the first option as indicated in the picture below, and then click "Next".


29. Windows setup will go through the necessary steps and eventually restart again, and when Windows starts up again, it will give you a "Display Settings" message, just click on "OK".


30. It will then display another message for the "Monitor Settings", click on "OK".


31. On the Welcome screen of Windows, click on "Next".


32. On the "Help Protect your PC" step, select the "Not right now" option, and then click "Next".


33. When checking for internet connectivity, you can click on "Skip".


34. On the "Ready to Activate Windows?" step, select the "No, remind me in a few days" option, and click on "Next".


35. On the "Who will use this computer" step, type in your name, and click on "Next".


36. The last step, the only option is to click on "Finish".


37. After that last step, Windows will show the desktop of Windows XP, and as far as installation is concerned, you are now finished.


38. OK, so now the Windows XP is installed. To enable us to work with this Virtual Machine successfully, we must first check if we have installed Windows XP Service pack 3. To do that, click on "Start", then "Right Click" on "My Computer", and then click on "Properties".


39. A "System Properties" window will appear, and you will see at the top of that page what Service-Pack is currently installed. If yours is Service Pack 3, then you are fine to continue to step 41. If it says Service Pack 2, then you need to download service pack 3 from the Microsoft website.

Download and install the service pack, this can take while.


40. After you have installed the service pack 3, go to the steps again and click on "Start", right click on "My Computer" and go to "Properties". It should then display "Service Pack 3". If this is correct, then we can continue to step 41.


41. Once Service Pack 3 is installed, you can click on "Tools" at the top of the Virtual Machine, and then click on "Install Integration Components". This is basically software that enables you to connect and use your Audio, Clipboard (for copy), Printers, Hard drives on the Windows 7 PC.


42. You will then get a message to install the integration components, click on "Continue".


43. The Windows Installer will start, give it some time to extract all the installation files, and it will start the "Virtual Integration Components" installer, click on "Next".


44. The installer will go through the necessary steps to complete and you will be prompted with a "Setup Completed" window. On this window, "untick" the "Download updates..." (Step 1), and then click on "Finish".


45. You will then be asked to restart the Virtual PC, click on "Yes".


46. After you rebooted the Virtual PC, and you still have the Windows XP disc in the computer, it might open the Setup for Windows XP (Because of the Integration Components now picking up the DVD drive from your physical computer in the Virtual PC). Just click on "Exit".


47. Now you can Install Caddie like you would normally do, but it the installation, do NOT install the HASP driver from Caddie. "Untick" the option and continue with the installation.


48. Now, Caddie needs a later version of the HASP driver than is provided on the Caddie disc, hence we didn't install it. If you have a newer Caddie disc like a Caddie 16 DVD, you can install it from there which will be shown in the next step. If you do not have a disc, please download the 

HASP Driver for Pre-Caddie 16 . 

Download it and follow the next step to install.

49. If you have a Caddie 16 Disc, browse to the disc. "Right Click" on the Start button, and click on "Explore". This step is the same for if you downloaded the driver.



50. As the image show here at the bottom, on the left pane, click on the Caddie 16 DVD (1) and browse to the "Pre-Caddie 16 Hasp Drivers" (3) folder which is situated in the "Drivers" (2) folder on the root of the disc. Double-click on the HDD32.exe file(4) to install the HASP driver.


51. When the HASP window appears, click on "U.S. English", and click on OK.


52. On the next step where it displays "Welcome", click on "Next".


53. On the "End User License Agreement" step, click on "I accept the license agreement", and click "Install".


54. When it says HASP Drivers installed successfully, click on "Finish".


55. After that step, insert your USB dongle. You will see a tab at the top that shows "USB". If you click on that, you will see that it shows a HASP HL x.xx and next to it "Attach". Keep in mind that if you have another version of Caddie because the dongle will not be usable there for as long as you use it on the Virtual machine.



56. Windows will detect the new hardware and will install the drivers for it.  This means that you will use the dongle on the Virtual machine. It will show at the bottom right corner what it is doing,and when it is complete it will say "Hardware is installed successfully and ready for use".



57. When that is done, click on "Start | All Programs | Caddie 9.1 | Caddie Info".


58. This will return the info of the dongle. Make sure it gives a HASP driver version of and that it also gives the correct dongle number.


59. If this is correct, click on "Exit".

60. Next we need to check whether the screen settings are correct. To do that, "Right Click" on your desktop background, and then click on "Properties".


61. On the "Settings" tab (1), make sure that you have the correct screen resolution, but more importantly, make sure it is set to "Highest (32 bit)" color quality (2). Then click on OK.(This is just to ensure that your buttons display correctly within Caddie).


62. Once this is all done, you have an option to make your Virtual PC use the full screen, you can do that by clicking on the "Action" tab (1) on top and then "View Full Screen" (2).


63. Now you can open Caddie from from your Desktop shortcut. The only thing you will need to make sure now is that is recognizes the license you are using (2).


64.And that is basically it! Now you can use Caddie as you always have.; If you want to use the dongle back into the other Windows 7, you can close Caddie and click on "USB" on top (1),and click on the HASP HL x.xx (release) (2).


65. If you want to shut down the Virtual PC, you can do that by normally "Shutting down". Click "Start | Shut Down". This should answer all your questions regarding how to get Caddie versions older than V16 working on a Virtual PC application from Microsoft.

Installing Caddie



Installing Caddie

Installing Vio

Running Caddie for the First Time

What To Do If Caddie Runs in Demo Mode

      Updating the Dongle Security Key


Mainenance Date Is reported Incorrectly

Installing Network Dongles


Please read the following guide before installing Caddie.

Using the standard options, the installation of Caddie should be straight forward.

The installation process will vary depending on the license you have. There are three types of license:

  • Softlock License

The  period of the license can be purchased. This is issued for a short term rental of Caddie or a Student license. At the end of the time period the license will revert to Demo

If no time has been purchased the license is Evaluation and lasts for 14 days. After 14 days the license reverts to DEMO. It can be converted to any other license at any time.

The licence for a softlock is a one off per computer, regardless of software version, and is not transferable between computers.

  • Hardware License (Dongle / HASP)

Full Caddie, needs a Hardware key which also needs an additional driver to be installed (see below)

  • Network License (Network Dongle / HASP)

Needs a special hardware key and additional License Manager software to be installed on the Network Dongle Server. This is covered at the end of this document.

Evaluation - The Evaluation license lasts for 14 days. Caddie will automatically be in Evaluation when Caddie runs for the first time or is the selected license.

Demo is a full installation without the requirement of any hardware or software license. The only limitation is the ability to save or copy drawings or drawing elements (including backups). Caddie will run in ‘DEMO’ mode when:

  • The Softlock 14 day evaluation period has finished
  • A hardware dongle is not present at the time of Caddie loading or it has been removed with Caddie running. Note if the dongle has been removed or has failed to work dure to system reasons, Caddie will need to be re-started with the dongle in place and working.
  • The hardware dongle has not been authorised
  • There are no more Network licenses available
  • Incorrect HASP driver has been installed


image004  If you have a security dongle install the software before plugging It in.

To install the software insert the DVD into your  DVD player and it will Auto Run.
If it doesn't run, use Windows Explorer to find the file ”Setupsplash.exe” on the root of the DVD and run it.


Full Instalation

From the dialogue, select Full Installation and follow the installation prompts and do a Typical installation. Caddie also requires some Microsoft TM Operating System files to be downloaded and installed. This will be done automatically so let caddie do this. If these are blocked by your fire wall or not run, Caddie will not run correctly.

Redering Extrension

This is normally installed at the same time as Caddie. If it need to be installed separately from the dialogue, select Rendering Extension to install Caddie Vio photo-realistic rendering integrated into Caddie Professional.

Symbol Library

You will normally be asked if you want to install the symbol library. If it needs to be installed separately, this can be done by selecting Caddie Symbol Library from the menu.

Training Videos

From the dialogue, select Install To Hard Disk to install the Caddie training videos.

Note these training videos are on the Installation disk and not the What’s new video disk. The Video disk is designed to play from a standard video recorder or a computer with the correct programme and drivers. Additional drivers for a computer can be found by “Browsing This Disk” from the installation menu and running the file in the “VLC” folder.


Plug Dongle In

(Skip this step if you have an Evaluation or a Time limited license.)

If you have been provided with a Dongle Key (HASP) then now is the time to plug it in. Insert the dongle into a convenient USB socket and wait for it to light.

Run Caddie

When Caddie runs for the first time there are a number of settings that need to be finalised so you will see the following dialogue.

(If this is a Caddie 18 reinstall, this step maybe ignored so go to  “What to do if Caddie runs in Demo Mode”)

  1. Select your region
  2. Select the License type.

Choose one of the following depending which licence you have (the introduction explained the various licence types).

  • I have a Dongle Key (HASP) choose

‘I have a dongle connected to this computer’

  • I have a network dongle choose

‘I connect to a network dongle on another computer’

(see separate instructions for installing a network dongle).

  • I have a time limited license (softlock), you will not have a dongle and you will have an activation code choose

‘I have a time limited software license with an activation code’

  • I am evaluating a version of Caddie for the first time

‘I don’t have a  Caddie License – I am evaluating Caddie’

If the Evaluation has expired Caddie will run in Demo Mode.

3.  Select the applications you want to load.0
  • A suggested selection is either ArchUK or SA_Arch and 3D.
  • (You can right-click on the Caddie application button when in Caddie to load and unload applications at any time.)
4. Once set select OK.

Caddie may restart a number of time during this proicess.


Caddie will run in Demo Mode if any of the following occurs

Your Time Lock period has elapsed

If you have an Education version or a load of caddie there will be a time period associated with you licence. Once this has expired caddie will revert to the Demo mode. If you need to extend this period Please contact Caddie. Note the softlock licence is on a per-machine basis and cannot be transferred. Contact Caddie for further information.

Your Evaluation period has elapsed

The standard evaluation period is 14 days

You haven’t inserted your HASP key (dongle) if you have one.

If you have a USB dongle. This needs to be inserted and lit in order for Caddie to recognise it and before caddie is run. If it is not recognised this can be because the drivers have not been installed or are to wrong ones for you operation system. If the dongle is lit then all you may need to do is fllow the instructions below, to obtain the security file.

Your need to obtain a security file

Your dongle may be lit but the security file is the incorrect one for your licence. If you are a maintained user then follow the step s below.


Updating the Dongle information

Go to the Help Menu and select ”Dongle Info” and you will see the dialogue below.
image037 image039
If you have a the software has been installed correctly, you should see the number of your dongle mentioned.

If it Has a number

  • You are running in either Evaluation or Demo mode. If this is required then there is nothing else to do
  • If you have a Softlock then you will need to activate your license. The easiest way is to connect your computer to the internet and select the ACTIVATE NOW button. Manual activating is also possible by selecting your required options.
  • If you have a dongle select the ”Download Latest Security File” button. Once done you will get the following  message.
Select 'YES' and Caddie will restart in the mode you are licensed for.

If you have a firewall or your Windows security blocks the replacement of the file you will have to first remove the existing one manually. To do this go to MENU | | HELP | WINDOWS EXPLORER. This should open Windows Explorer at the Caddie folder. Find a file called MSDBUTILS.DLL and delete it. Now try the Download Latest Security File“ again. 

If dongle number is blank

If you have a Dongle and it is plugged in and lit, run the  Uninstall Hasp Driver followed by a Reinstall Hasp Driver from the Hasp Tools Tab. Note the driver installed should be as shown or higher. 

  • See the Caddie Web Site (FAQ) for further information regarding Windows Permissions.
If  this still doesn’t produce a number then please contact Caddie (ACS).


Caddie has an inbuilt notification of the maintenance date for the dongle currently plugged in. This date is normally set from the online database and in some cases may take some time to update. However if you wish you manually update the date for the dongle, go to HELP > MAINTENANCE INFO. If you don't know what your maintenance date is, contact Caddie support.

Tick the box “I have renewed my maintenance” and set to date to the correct date of maintenance expiry. If this is unknown, contact Advanced Computer Solutions for the date on record.

Note: If this is the first year of using Caddie then the date will usually be the initial invoice date. If you have already updated your maintenance an email would have been sent with the new expiry date. In some cases the invoice for any updates may include the expiry date.





Before installing the Network Dongle

On workstation on the network will act as a ’Dongle Server’. It is not necessary that this server has Caddie install but before we install the necessary Net Dongle Licence Manager, we need to ensure the dongle drivers are installed. This can be done by installing Caddie from the Install Menu on the CD (as already mentioned). If Caddie is not required on this workstation then just install the HASP driver (also on the Install Menu).

On the Dongle Server:

Using Windows Explorer find and install the latest Hasp driver from the Drivers / Aladdin folder of the Caddie CD.
Find the Licence Manager in the Net Hasp Files folder on the CD (LMSetup.exe) and OPEN (run) it..
image048 image050
Check the driver is 8.32 or higher. Select ’NEXT’ Accept the licence and click ’INSTALL’
image052 image054
You can install the Licence Manager as a service or
load it at start up. It is  preferably to load it as a Service.
Select the required option and ’NEXT’
Use the default install path (you can change it if required).
Select ’NEXT’
image056 image058
Use the provided group name and ’NEXT’ Select ’NEXT’ and the Licence Manager will be installed.
If you have a Network HASP plug into a spare USB
socket and wait for it to light. If it doesn’t light reinstall
the HASP driver from the Install menu on the CD or
form ’CADDIE | HEPL | DONGLE INFO’ and the
HASP TOOLS tab (see above).
Then select ’FINISH’

On the Caddie Workstations

The HASP drivers for dongles will be installed when installing Caddie on other workstations.
image004  This next step is important
On the workstations requiring to use the Network Hasp, run Caddie and go to ’MENU | HELP | DONGLE INFO’. Choose the ’Check For Network Dongle First’ from ’DONGLE TOOLS’ tab and restart Caddie. 
After following the above procedure, the Network dongle should work. 

Setting the Network Address

To change the way the local workstation finds the Network dongle, go to ’MENU | DONGLE INFO’ and choose the ’Network’ tab’ Firstly try setting the network path to AUTO.
If the dongle still can’t be found ask your network manager to enter the correct IP address and other require details.

Installing Caddie 18 on a Microsoft Windows 8 Computer

Applies to

Caddie 18 and later. Note that no previous versions will work on Windows 8


When installing Caddie on a computer with a Windows 8 operating system, Caddie fails to find the dongle. What do I need to do?


Currently the installation of the dongle driver (HASP driver) on a computer with a Windows 8 operating system requires a different driver from the default one installed. This driver will have to be installed after Caddie has been installed.


If Caddie 18 was installed from a DVD there will be a file with the following name in the specified path



If you do not have a disk for Caddie 18 the Windows 8 dongle (HASP) driver can be downloaded from here


Note: you will have to login for permissions to download this file.


After Caddie is installed run the dongle (HASP) driver that you have (disk or download as mentioned). This will install the correct driver for Windows 8.

To Install

  • Download the file to the local computer (make a note where it is saved).
  • Right Click on the downloaded file and select 'Send To', Select 'Desktop (create shortcut)' from the list that appears.
    This will create a shortcut on the desktop.
  • Locate the shortcut and right click it then select Properties.
  • In the 'Target' box add  -r to the end of the line (Note this is a space followed by -r).
    The target will now look something like:

C:\Downloads\Caddie_Hasp_6_51.exe -r -purge (assuming the file was downloaded to 'c:\Downloads')

  • Select OK to close the dialogue.
  • Double click the shortcut - A small progress box should be displayed and after a few minutes it should read 'Operation Completed Successfully'.
  • Click OK to close the progress box.

If User Account Control is set to a high level, you may have to confirm your permission for the program to run.

  • Locate the shortcut again and right click and select Properties.
  • In the 'Target' box, change the last character from r to i.
    The target will now look something like:

C:\Downloads\Caddie_Hasp_6_51.exe -i (assuming the file was downloaded to 'c:\Downloads')

  • Select OK to close the dialogue.
  • Double click the shortcut - A small progress box should be displayed and after a few minutes it should read 'Operation Completed Successfully'.
  • Click OK to close the progress box.

If User Account Control is set to a high level, you may have to confirm your permission for the program to run.

The above assumes that the latest driver downloaded was Caddie_Hasp_6_51.exe. Change the name in the above commands as appropriate for the version downloaded

The hasp driver is now installed

Note: You must have administrator permissions to perform the above task.

If for any reason any of the above tasks fail, then you should change the User Account Control (UAC) settings.

To do this type UAC in the Start menu search bar and choose "Change User Account Control". Change the slider to the lowest level.

Also set the Privilege level by right clicking the shortcut and from the Compatibility tab tick the  'Run as Administrator' tick box, and retry.


To check that the driver is correctly loaded open a web browser page and go to: //localhost:1947

If the driver is correctly loaded that should take you to the Sentinel Admin Control Center Page where you can see the status of your dongles and softlock licenses. If you are unable to display the page, check that the driver was installed correctly and also check that you have no firewalls etc. blocking access.

Caddie Only Starts in Demo Mode


Caddie 16 and above


I am a registered user of Caddie but when I run a newly installed Caddie I get a Message saying:

"No Dongle found or you are not authorized to use it.
Continue loading the DEMO version?"


You may get this message for a number of reasons.

  • You installed a copy of Caddie that didn't recognise your dongle.
  • You are not licensed to use this version.
  • If you have a dongle it is un-plugged.
  • The Dongle has not been correctly installed.

If you have a USB dongle check that it is lit.

From Caddie 16 a new Dongle driver is used. This new driver is compatible with all USB dongles and some later Parallel Port dongles. If your parallel port dongle has the embossed word "HASP" followed by a registration mark then it will need to be changed. If after following these instruction you still have problems, contact Caddie support.

  • You are not authorised for this version of software.


If you have a dongle but haven't plugged it it, cancel Caddie, plug the dongle in and restart Caddie.

If you are using Windows Vista, Windows 7 or Windows 8 run 'Administrator Mode'. To do this right click the Caddie icon and select 'Run As Administrator'.

If using Windows XP, just run Caddie.

In all cases run Caddie in demo mode. Caddie will check that the dongle and the licence file match. If they don't you will be invited to download the latest security file.

You will be taken to the 'MENU | HELP | DONGLE INF dialogue.


If the dialogue isn't displayed, use the Help menu to open it.


If the dongle driver has been installed correctly, you should see the number of your dongle mentioned.


If it has a number


If you have a dongle select the ”Download Latest Security File” button. Once done you will get the following message.


Select 'YES' and Caddie will restart in the mode you are licensed for.

Your firewall or your Windows security may block the automatic replacement of the file. You will have to first remove the existing one manually. To do this go to ’MENU | | HELP | WINDOWS EXPLORER’. This should open Windows Explorer at the Caddie folder. Find a file called MSDBUTILS.DLL and delete it. Now try the ”Download Latest Security File ” again.

If dongle number is blank If you have a Dongle and it is plugged in and lit, run the ”Uninstall Hasp Driver” followed by a ’Reinstall Hasp Driver’ from the ’Hasp Tools’ Tab. Note the driver installed should be as shown or higher.

See the Caddie Web Site (FAQ) for further information regarding Windows Permissions.
If you still have problems, contact support for further assistance.

Importing Screen Layouts From Previous Versions

Applies to

Caddie 17 build 2 and later


How can I import a screen layout from a previous version of Caddie?.




Caddie 17 build 2 has a new direct import of screen layouts from Caddie 16. After installing Caddie 17 you will be asked if you want to migrate your settings from a previous version. If you select 'Yes', one of the options will be to import your screen layout.


If you have already been past this step and resplied 'No', you can get back to this option at any time by going to Utilities -> System -> Migrate Settings from Caddie 16.


Note that this option is only valid for importing settings from the previous major release of Caddie.

An error occurs when accessing Help Dongle Info

Applies to

Caddie 16 and later

Windows 7


When accessing the Help -> Dongle Info command Caddie throws an error.




This can occur if the softlock licence was not correctly installed. To rectify the problem try the following:


From the Start Menu right choose All Programs -> Caddie 17 then from the options, right click Custom Hasp Driver Installer and choose run as administrator.

The installation should complete without any errors. If an error occurs, download the latest driver from the hasp website -


At the time of writing, the download page is:


The driver to download is the latest Sentinel HASP Run-time GUI Installation. After downloading it run the installation. After completing the installation repeat the first step as follows:


From the Start Menu right choose All Programs -> Caddie 17 then from the options, right click Custom Hasp Driver Installer and choose run as administrator.


This time the installer should prompt that a later driver is already installed and only the licence file will be installed. Click OK to confirm


Start Caddie and check that the Help -> Dongle Info is now ok.


Why can't I save my Screen Layouts?

Applies To:

Caddie 16 onwards

Windows Vista, Windows 7


I try to save a screen layout and I get the message there is no layout to save. What is the problem?


I try to import a screen layout, but nothing changes, why?


This is usually only with a 64 bit operating system and is usually due to the security settings on your computer.

In order to save a screen layout or to import a screen layout, Caddie must be run as an administrator. To do this run Caddie by right clicking the Caddie launch icon from the Start | Programs menu and choose 'Run As Administrator'.


You can not do this from a pinned icon on the Quick Launch bar.

Microsoft .NET Framework Install error

If you have tried to install Caddie 17, and you received an error with the .NET 4 Framework installation, this article could help you to solve the problem.


The .NET Framework is a prerequisite that enables Caddie to run.  Caddie 17 requires .NET 4 Framework to be installed in order to be able to open and run successfully.


So if you received the "HRESULT: 0xc8000222" error with the .NET installation, according to Microsoft's website "This behavior may occur if the temporary folder of Windows Update has been corrupted".


According to the Microsoft support website, that temporary folder needs to be renamed and the following steps can be taken to resolve the problem:

You can be assured that the folder will be created again once you visit the Windows Update site again.


  1. Click Start, Run, type: cmd and press Enter. Please type the following command in the opened window.

    net stop WuAuServ
  2.  Click Start, Run, type: %windir% and press Enter.
  3. In the opened folder, rename the folder SoftwareDistribution to SDold.
  4. Click Start, Run, type: cmd and press Enter.

             Please run the following command in the opened window.

             net start WuAuServ

       5.  Type exit and press Enter.


Now you should be able to run the .NET setup again, this time from the Caddie installation disc.  To do that, please follow these steps:


  1. Browse to the Caddie 17 Disc, by clicking the "Browse This Disk" option from the setup menu.

  2. Open the "Prerequisites" folder and run the "dotNetFx40_Client_x86_x64.exe"
  3. Continue to go through all the steps and finish the installation.  It should now install without any errors.

Caddie will now be able to run successfully without any problems.  Please contact Caddie Support if you need any further assistance.


MSVCR100.DLL is missing


  • Caddie 18 and later


Trying to start Caddie I get a message stating MSVCR100.DLL is missing


Caddie requires the Microsoft Visual Studio 2010 C++ redistributables to be installed on the PC. These can be downloaded directly from the microsoft site. 



Should I use a Peer to Peer or Domain based network?

This is a question we hear frequently.


 A peer to peer network is a configuration that was  popular in the early nineties with the release of Microsoft Windows for Workgroups. Peer to peer networks were easy to setup and required only a basic knowledge of computer networking. In Windows XP, this technology is often referred to as "File & Printer Sharing."

Many businesses resist establishing a domain due to their belief that a peer to peer network is quicker and therefore cheaper to setup. However, establishing a domain provides your business with a complete business solution that will serve your needs now and into the future. It provides you with a central location from which to manage your network - simplifying your network and therefore dramatically reducing technical support and associated costs.


The following are the basic differences between the two architectures:

The Peer To Peer Network

  • A peer to peer network does not require a server. However it is not uncommon for users to designate one machine as a server on the network, configured like any other workstation.
  • In a "peer to peer" network, each workstation on the network must be separately configured.
  • The management of the network is spread out amongst all workstations on the network. When a technical issue arises, it often has to be addressed on each workstation.
  • For each user to have access to each workstation, a user account must be created on each workstation.
  • Shared drives must be mapped manually from each workstation.
  • Shared printers must be manually connected and printer drivers installed on each workstation.
  • The user account names must exist and match on each machine where document sharing is required.
  • In a peer to peer network, company data and electronic mail is stored on various workstations throughout the network rather than being stored in one central location. The daily backup job if one exists is therefore not able to backup all company data because it is not in one central location. Backup becomes laborious and is often neglected.

The Domain Environment

  • The domain environment requires a server running the Windows Server operating system. The server is then configured as a domain controller.
  • The user accounts for the network are created in one place - on the server. The workstations on the network are then simply joined to the domain which allows staff members to utilize their user accounts.
  • The management of the network is conducted from one place - on the server. When a technical issue arises, it is typically addressed from one place (on the server) which often resolves the problem for the workstations on the network as well.
  • When a user logs in to the network, the server grants access to files and directories as defined by the business owner and/or network administrator. In addition, they are passed through a login script which maps common network drive letters throughout the network.
  • For a user to have access to a printer, they are simply connected to a print queue on the server. The print driver is only installed once on the server and the workstations are then connected to the print queue.
  • All data in the domain is then typically stored in one place - on the server. The daily backup then ensures that all data such as company files and electronic mail are backed up from this location on a daily basis.

From the above information you can see that although the initial outlay on hardware and software may be slightly higher establishing a domain based network, the long term and even short term costs will be significantly less if you take into account time. Coupled with the fact that data security and integrity are significantly better, for most businesses the domain model is the only one that makes sense.



Caddie 9 and 64 bit Windows 7

Why does Caddie 9 not recognise my dongle on 64 bit Windows, or Windows 8 (32 bit) or later?


Caddie 9 uses various components developed by other companies. One of these is the driver for the dongle. The dongle driver in Caddie 9 was developed approximately 18 years ago. It was developed for Windows NT4 and Windows XP. This was long before Windows 7 was developed so the developers could not anticipate the requirements for 18 years in the future. Windows 7 requires a completely different driver architecture, which has been implemented in later versions of Caddie using modern versions of the dongle driver.


Can Caddie 9 use these later drivers?


No. Many of the 3rd party modules in Caddie 9 are now obsolete. In fact many were obsolete by the time Caddie 10 was launched - one of the many reasons for the different look to the interface. The newer dongle drivers require that the software is compiled with a modern compiler - they will not compile using 1990's technology. Equally many of the components in Caddie 9 will not compile with a modern compiler - they require a 1990s compiler. It is therefore impossible to combine the modern dongle driver with the other components in Caddie 9.


Is there a solution?


Yes, there are two solutions. The best solution is to upgrade to a modern version of Caddie - the current versions of Caddie are available for 64 bit versions of Windows. If for some reason you are unable to run a current version of Caddie, Microsoft provide a utility called a virtual PC (Windows 7) or Hyper-V (later versions of Windows), specifically for running older obsolete programs. Depending on your version of Windows, Virtual PC / Hyper-V will either already be included, or it must be downloaded separately.


See this Microsoft Article for more information.  For further information on how to set up a virtual PC, click HERE . 
Please note that according to Microsoft "Windows Virtual PC" is only supported on Windows 7 Professional and Windows 7 Ultimate.  And it doesn't support parallel ports, so if you have a parallel dongle it will have to be exchanged for a USB one.
Also note that Caddie no longer offers support for versions of Caddie older than approximately 8 years - see this article for the current support status.

How can I pause and re-start a download of large files

Applies To

No specific operating system or Caddie version


When I download Caddie, which is a very large file, my connection sometimes breaks and I have to start all over again. I also have a very slow connection and I would like to speed this up and have the ability to break the download up into small chunks. Is there a way to do this.


Yes there is a way to do all of these things. What  you need is to download and install one of the many download accelerators or download managers. There are many available. Some have to be paid for, some have free limited use and some are totally free. Even the paid for versions usually have a free trail period. Some work standalone and some will be installed as add-ons for your favourite internet browser.

Which ever you choose they all will resolve the three main requirements.

Speed up the download time.

Whilst these programmes don't really speed up the download, what they do is to make more than one download connection  and split the download over these connections and reasemble it after the download. The net result is a faster download.

Restart the download without restarting from the beginning again

Because they way these accelerators work, they are able to recognise how much of the download has been made, so that in case of connection breaks, a restart will first check the position of the previous download and restart from that position. So in other words, if 80% had been downloaded then when a  download of the same file is down only the last 20% will need to be downloaded.

Pause the download

Similar to the last requirement, the download can be paused and then resumed at a later time.

In addition some will even send you computer to standby, hibernate or even shutdown, so you can leave it running and when it is finished downloading your computer will do what ever you have selected.

What one you use will be up to your personal preference.


Here are a couple to lookout for.



Speedbit home page

DAP can be integrated with various browsers such as Microsoft IE, Firefox, Google Chrome, Opera and Netscape.

This seems to be the web favorite.



IE6,IE7,IE8 and Firefox are supported


Internet Download Accelerator

For Google Chrome users there is this extension



After a downloading check the size of the downloaded file matches what is stated on the Caddie site. If the size if different from that stated, i.e it is too small, it is probable due to a firewall not allowing access to the download. This can be rectified either by setting your firewall to allow your download manager to connect automatically or temporally  unblock you firewall.

ACS (Caddie) does not endorse any of these or other download accelerator products and therefore can not offer support for them. Please use the providers sites for support. 



Caddie says Softlock Not in Use or is Expired

If a previously working Caddie says 'Softlock not in use, or is expired' there may be several causes.



1. The softlocks are time limited and may have expired

2. Caddie may be unable to communicate with the softlock due to firewall issues etc. (Caddie requires port 1947 to be open)

3. The Sentinel Hasp license manager may have stopped


To check if the licence manager is stopped, From the start menu type services.msc into the search box and the services dialogue should open. Scroll down to find Sentinel Local License Manager and ensure it is running. If not select it and click the Start option. Close the services dialogue and restart Caddie.




Alternatively, restart the PC and the license manager should be restarted automatically.

Caddie doesn't want to open on Windows 7

Applies To

All versions of Caddie from Version 16


If you are experiencing problems with Caddie not opening on Windows 7, either giving you an error straight away or just opening and closing in the processes (Task Manager), it could be that you do not have an appropriate screencard driver.  It is not the definite problem, but it is a step towards eliminating the elements that could cause the problem.


Please note that this is not applicable to you if your Caddie has opened before on that exact same PC and operating system.  This is if your Caddie doesnt want to open First time around.


The problem here is that when your Windows 7 was installed, it installed a screencard driver that was from Microsoft.  This is a very nice feature from Windows 7, but this driver is not designed for applications that need hardware acceleration standards such as the drivers from the Manufacturer of the screencard itself.  And this is where the problem lies.  You need to update your drivers to the latest manufacturer driver.

To troubleshoot your problem to see if you are on the right track, you can do the following check:


1. On your Desktop, right click and go to "Screen Resolution". 




2. On the right hand side, click on "Advanced Settings"




3. Then you will see you current screencard name.  And if it has the Microsoft driver installed, it will show in brackets next to the name (Microsoft Corporation XXXX).  If this is the case, the first step will be to download the latest drivers from the manufacturer website for that specific screencard, and install it afterwards.  If this still doesnt sort out your problem, please contact Caddie support.




How to install the HASP Driver on Windows 7

To Run Caddie on a Windows 7 computer the latest HASP Driver (dongle driver) is required.

To Install

  • Download the file to the local computer (make a note where it is saved).
  • Right Click on the downloaded file and select 'Send To', Select 'Desktop (create shortcut)' from the list that appears.
    This will create a shortcut on the desktop.
  • Locate the shortcut and right click it then select Properties.
  • In the 'Target' box add  -r to the end of the line (Note this is a space followed by -r).
    The target will now look something like:

                   C:\Downloads\haspdinst.exe -r (assuming the file was downloaded to 'c:\Downloads')

  • Select OK to close the dialogue.
  • Double click the shortcut - A small progress box should be displayed and after a few minutes it should read 'Operation Completed Successfully'.
  • Click OK to close the progress box.

            If User Account Control is set to a high level, you may have to confirm your permission for the program to run.

  • Locate the shortcut again and right click and select Properties.
  • In the 'Target' box, change the last character from r to i.
                     The target will now look something like:

                 C:\Downloads\haspdinst.exe -i (assuming the file was downloaded to 'c:\Downloads')

  • Select OK to close the dialogue.
  • Double click the shortcut - A small progress box should be displayed and after a few minutes it should read 'Operation Completed Successfully'. 
  • Click OK to close the progress box.

            If User Account Control is set to a high level, you may have to confirm your permission for the program to run.

The hasp driver is now installed.

Note:     You must have administrator permissions to perform the above task.

If for any reason any of the above tasks fail, then you should change the User Account Control (UAC) settings.

To do this type UAC in the Start menu search bar and choose "Change User Account Control". Change the slider to the lowest level.

Also set the Privilege level by right clicking the shortcut and from the Compatibility tab tick the  'Run as Administrator' tick box, and retry.


I get 'Side by side configuration' error when first starting Caddie after installation

Cause: The error message can be caused by the Visual Studio C++ 2005 Redistributable not being installed on the computer.

Solution: Download and install Microsoft Visual Studio C++ 2005 redistributable from the Microsoft website (

What versions of Windows will Caddie run on?


Caddie 9.1 will run on Windows XP, Windows Vista and Windows 7 but only 32 bit versions. Version of operating system later than Windows XP may also change some of the functionality.

Caddie 9.1 will not run on Windows 8

Caddie 9.1 will not run on any operating system that is 64 bit.

It is possible In order to run these (excluding Windows 8) a Virtual OS has to be set up.

There is a FAQ elsewhere that describes how to do this.

Other versions prior to Caddie 15 may also be affected

All versions of Caddie from version 15 will run on 32 bit and 64 bit versions of XP, Vista and Windows 7. Only Caddie 18 is qualified to run on Windows 8


   windows8-compatability logo

When I install Caddie it prompts to install a HASP Driver. What is this?

The HASP driver allows Caddie to communicate with the dongle (HASP) - the security device which is plugged into either the parallel port or the USB port.

Key Words

Dongle, HASP, Caddie, Demo, Installing, CAD.

How much RAM is required to run Caddie?

The amount of RAM that versions of Caddie 15 or higherof required depends on the operating system and what other applications will be run on workstation. Caddie can not be installed on any computer with less than 1 GB of ram. It is preferably to use 2 GB or 4 GB for larger drawings and 3D work.

If 4GB of RAM is installed on a 32 bit computer only around 3.5GB maximum will be used (an operating system limit).

On 64 bit machines it is recommended to install 8GB of RAM.

It is also recommended for versions of Caddie 17 or higher that a 64 bt machine with at least 8GB of RAM is used.

What are the recommended video cards for Caddie?

Caddie 15 and later uses OpenGL graphics libraries, so graphics cards specifically designed for OpenGL such as nVidia's Quadro range and ATI's FirePro range will give the best performance.

On board graphics should be avoided as these are generally designed to be used with general office software and not CAD or 3D programmes such as Caddie. If your computer has only an on board graphics processor (usually identified buy the graphics connector being one of the group of other connectors), purchasing and installing a standalone graphics card will greatly improve the display capabilities of your computer. 

I currently have a Parallel dongle but my new computer doesn't have a parallel port. Can I change it for a USB dongle?

Yes you can. You can return your dongle to your local supplier and they will supply a new USB dongle for a small charge.

Why does Caddie require a dongle?

Caddie requires a dongle to enable the save drawing function. Without a dongle all the main functions are available except for the save drawing and Vio rendering functions.

Do I need to uninstall my old version of Caddie before installing Caddie 15?

No you don't. Caddie 15 will co-exist with earlier versions on the same workstation.

I have several CTB plotstyles from my old CAD system. Can I use these with Caddie?

Yes you can, on all versions of Caddie since Caddie 10. Copy the plotstyles into the plotstyles folder and Caddie will use them. To find out where the plotstyle folder is located, open Caddie then go to Settings -> Environment Settings and expand the Folders option.


Use the same technique if you get a plotstyle when you receive a drawing from a colleague that you are working with.


On Caddie 16 and later, you can get to the default plotstyles folder very easily by going to Utilitiess -> Browse -> Common Application Data Folder. In the list of folders you should see one called Plotstyles.

Can I use Caddie on a dual screen workstation?

Yes you can.

Can I install Caddie 15 on several computers without violating the licence agreement?

Yes you can. Caddie can be installed on as many computers as you like. However if you wish to save your work, when you start Caddie the dongle must be plugged in to that computer and must remain in for the entire working session. So if you want to use Caddie simultaneously on more than one computer you will need to purchase additional dongles (licences).

I have various .pat hatch patterns from my previous CAD system. Can I use these with a later version of Caddie?

Applies To

All versions of Caddie from Version 15


Yes you can. Copy the .pat files into the hatch folder and Caddie will use them. To find out where the hatch folder is located, open Caddie then go to


and expand the Folders option.

Alternatively (if using the default folders) go to


This will open Windows explorer. There you will see a folder named "HATCH". It is in this folder where the Custom Hatch patterns (*.PAT) are stored. Caddie will automatically pick these up when required.

Architect, Richard Likupe on the UK Launch of Caddie 25, and the benefit of upgrading

''The new functionality on display at the UK launch of Caddie 25 more than met my expectations, and I congratulate the whole team for their hard work in improving an already great program. This will make it easy to demonstrate to new people what CAD can do. 
Using the new software is a revelation too, from the first moment I opened Caddie 25, I found it so much faster than my previous versions; and with thousands of new Catalogue items to choose from it’s easy to create high-quality drawings and models quickly.
In short, I’m a very happy Caddie customer.'

In-place Block Editing with greying out of remaining drawings Objects

'Just a quick one to thank you so much for the excellent feature regarding the block edit where everything else is greyed out.  It really is little tweaks like this that makes Caddie so good.  It is fantastic and not only tells you that the block is being edited, it makes it much easier to see and edit.'

Matthew Goddard BSc(Hons) MRICS
For and on behalf of Asset Construction Consultants.

Steve Harrop discusses the importance of good customer when choosing a CAD system.

'When I was deciding which CAD system to buy I tried ringing their support numbers at 16:45 on a Friday.

Company one, NO ANSWER.
Caddie support answered, 'Afternoon Steve, how can we help you today'?
Help when you need it makes a big difference. (Especially in my case!)'

Steve Harrop


The migration between Caddie 12 and Caddie 14 is seamless. You can’t see a difference until you start to experiment with all the new functions. The backup support form Caddie is still a constant and always satisfactory.

‘The Caddie YouTube videos are the best thing you've done, and absolutely essential when one lives and works in north of Scotland as I do; whilst I don’t take in this kind of information too well over the phone I can watch the videos in any spare moment I get, even late at night, and this makes them ideal for keeping me up to date.’

Hugh Mackay, Drafting Services


"The new PDF underlay feature is going to save so much time. The ability to snap to precise points on a PDF drawing is really quite amazing; no more guessing and freehand approximation."


Dan Kantorowich


After doing the three day Quick Start Course I drew quicker on Caddie than on my old system

James Morford comments on why choosing Caddie CAD software has proved to be a great decision for his practice, providing a simple, easy to use way of creating .DWG architectural drawings backed by outstanding support.

'I have been using Caddie for 18 years now and seen how the software’s ability has progressed with time to meet clients expectations. I personally don’t use the 3D capabilities but the software’s ease of use and simplicity have been instrumental in my drawing efficiency and quality. I would highly recommend Caddie to any Architectural company. The technical support is outstanding and easily understood. All of my drawings are in .dwg format so I work seamlessly with engineers etc….'

You have always been very prompt in dealing with any problems we have encountered, a service essential for the smooth running of the practice, so many thanks indeed.  The fact that the relationship is personal and not via some anonymous help-desk is very important to us as our practice has been built upon personal relationships with clients and providers alike. We hope that relationship will sustain far into the future.'

Philip James of Philip James Architecture reflecting upon his recent move to using Caddie;

'I should have done this years ago...when you first came to see me, in fact!'

I have just had my most productive year ever - and that is largely due to using your Caddie software.

Caddie saves me the equivalent of two staff

Colin Logan of 9yards Property Ltd. reflects on how much faster he can draw his architectural plans now using Caddie's smart AEC Build tools...

'I now use Caddie’s AEC Build tools for all my architectural plans, drawing complete and fully hatched walls at a stroke, and adding doors and windows just as easily.

Amazing to think that I used to draw all my walls manually, creating lines and offsets then hatching them all in individually - What a chore that was!'

Caddie user Mark Brown of  WW Brown & Sons commented on the value of the support he gets through the Caddie Maintenance programme;

'We would have no hesitation in recommending Caddie.  We have found Caddie support to be extremely responsive, assisting with any of our queries promptly over the phone and providing invaluable follow-up information'.

A longstanding Caddie user's comments on the value of the support he gets through the Caddie Maintenance programme;

'Before calling Caddie support I had spent about an hour attempting to work out why I could no longer enter figures into my Construction Line offset command, but when I called the Caddie support guys, they quickly identified my problem and helped me fix it.  It turns out I had caught the 'NumLock' key by accident changing the function of the number pad keys on my keyboard!

I find the support I get through Caddie Maintenance invaluable, and paying for my maintenance by Standing Order means that I can pick up the phone and ask for help any time I have a problem.'

Peter Fishenden discovers how easy Caddie 20’s ‘AEC Build’ tools are to use...

'What can I say, WOW!

I was amazed by just how easy Caddie 20’s ‘AEC Build’ tools are to use, and genuinely gobsmacked at the results I was able to produce in such a short space of time.  In just over 20 minutes I managed to produce a complete model of my building, even including the roof, which I could view in the form of plans, elevations, or full-on 3D model – and this I’m especially pleased about since it now allows me to show exactly what is going to be built in a form that everyone can understand, not just for those who can read plans and elevations.'

‘Caddie Tea Break Tutorials’

Just a quick email to let you know that we were very pleased to be part of the tutorial yesterday. It was a great way to see what the function does, and so much better than reading about it! 

I look forward to trying it out, once I have got the latest version of 19 downloaded.

Andrew Dukesell

Good tips as ever, really like the polygon selection, I wasn't aware of that.

Very useful.


Philip James

Some really useful tips.

Amazing that I couldn't draw a line a few weeks ago.  Picking it up very quickly.  Many thanks to Tony for his unbelievable patience!! Wish I did this years ago.


Allister Godfrey

Andrew thanks again for a very instructive video, I had forgotten about the poly select ... that's gonna be another of those tools I can't live without!


Allister Godfrey

OMG... I use copy and increment on text A LOT, but I have never paid any attention to copy multiple in the list ... genius!


Andrew, thank-you once again for a VERY informative video!

Unique access to Caddie's development

‘Almost immediately after switching from AutoCAD to Caddie I realised that Caddie had some big advantages and just how unique Caddie is in giving every user such direct input into the way the software is developed, even for small practices like mine.  Whether it’s the fact that it’s a lot more ‘English’ in the way it works or the invaluable and extensive support, be it tweaking an existing command or adding new functionality to solve some new problem; it’s always possible to speak directly with the Caddie guys and get our ideas built directly into the software; incredibly useful, and very refreshing.’

‘Caddie Time-tracker takes the embarrassment out of billing!’

‘Caddie’s Time-tracker enabled me to produce a full listing for all the time I had spent working on my client's drawings at the push of a button.’

‘the Time-tracker printout, detailing ‘Work Time’, Open Time’ and Saved Time, along with the actual time and dates of the drawing sessions made the job of agreeing on the bill easy’

Stewart L Thorley, Building Plans & Design

I first came across Caddie several years ago (I think it was version 8!) and with every new release it just gets better and better. I believe that it is unique in giving every user direct input into the way the software is developed and the fact that the relationship is personal and not via some anonymous help-desk is very important to us. It’s always possible to get a query answered quickly and efficiently which is essential for the smooth running of our practice.

Sebastian Walsh - Hibbs and Walsh Associates Ltd

My skills have developed rapidly with Caddie and I believe it allows me to produce excellent drawings far quicker than any program I have ever used

Melvyn Shackleton commented on the value of the support provided for Caddie by ACS Ltd.

'If you want your drawing problems sorted rapidly, go to the experts, call Caddie support!'

Ross James of James Steel gets some help from the Caddie Support Team in streamlining his workflow;

'Thank you for your help on Wednesday you were very fast to give me a fantastic solution which will save me a lot of time and effort in the future fantastic service as usual.'

Kind Regards

Caddie user John Fenton on finding immediate benefit from updating to Caddie 25.

'I had thought that I would need to spend money upgrading my Graphics Card ,but switching to Caddie 25 solved my 'Long Pointer' screen drag problems at a stroke. Brilliant!.'

"These training videos are awesome - there is so much more to Caddie and its  great way to discover its full potential."

Graham Rocher 

After doing the three day Quick Start Course I drew quicker on Caddie than on my old system

'Thank you for the latest You Tube link. Very helpful - have been doing this stuff manually; it is great to see that it can be done automatically.
Look forward to the next YouTube training tip.'

“I’m not used to support like this – if more people realised how good it was they would also be using Caddie.”

“Thank you very much for your commitment to us - the Caddie Users"

The key to successful implementation is effective training

The Tea Break Tutorials are a revelation!

'For anyone who doesn’t benefit from  an office full of CAD savvy colleagues, or enjoy the luxury of a dedicated  iT department, the Caddie Tea Break Tutorials are a brilliant, short, fast, and easy way of picking up those tips and techniques that can really speed up everyday working.'

Ian Collier Chartered Architect

Even working on archived drawings is quicker with Caddie

'I now find it quicker and far less painful to export drawings from my old CAD system so that I can load and work on them in Caddie, even if it’s only a 10 minute job!'

Anthony Staig IBC Architects

Caddie is incredibly quick to use, and also most importantly it’s very easy to learn, irrespective of your previous CAD experience

Caddie  - the 'Complete Package'

'We are very impressed and excited about Caddie. It is inspiring to see everything that Caddie can do and it is a major advantage that you have someone you can talk to about needs and implementations to increase productivity.

Finally there is a "complete package" and we can proudly say that we are part of the Caddie family.'

You wouldn't recognize the office now, there is no drawing board, just my Caddie workstation

Updating to the latest Caddie is simple, with inbuilt auto-configuration and migration tools; but with Caddie Remote Assistance you can have the latest updates installed and configured for you, like Martin McGahon of Town & Country Planning Ltd.

'The ACS Support guys were fantastic!

They installed the latest Caddie software update for me, even migrating all my settings, completing the process in a matter of minutes and making the whole upgrade process seamless'.

“What we needed was stability and ‘DWG’ compatibility. Caddie has provided both”

'Loving the scroll through the paper sheets ideal for larger projects when we have loads of paper spaces.'

Andrew Dukesell, principal of DBD Architectural Consultancy Ltd., commenting on some of the new functionality available in Caddie 23


Joe Snape discusses how Caddie gives him complete freedom to design, and how the one on one support provided by the Caddie team has enabled him to develop his CAD skills from simple 2D plans to fully rendered 3D architectural building models.

'I find Caddie such a fantastic program to work with as it enables me to create everything I need, no matter what type of drawing or modelling I need to do, with the only limit to what I can design and produce is my own creativity.  The Caddie support team are superb too, with Andrew and Sam from ACS Ltd. going well above and beyond to help me whenever I’ve needed assistance.
Before I switched to Caddie, I would struggle to produce even basic CAD plans, but now, thanks to the help and advice I’ve had from the support guys over the last 3 years I’m creating full 3D building models complete with life-like material textures too.  The building models I create enable me to produce all of my 2D plans, sections and elevation drawings, plus the 3D views rendered views that enable my clients to get a great understanding of how the finished building will fit into its surroundings.  I don’t believe that I could have made such huge strides with any other system and cannot praise Caddie and Caddie support enough for helping me to achieve this, they have been excellent, A* Service.’

Joe Snape


Having been a KUHLMANN drawing board user in the 80’s I felt safe in the sense that I wouldn't have to adjust to the new technology “Computers”. Then I was introduced to the DOS version of CADDIE. We upgraded to CADDIE 5 Professional and used the programme until the hard drive of the computer gave up and I was forced to upgrade. We installed CADDIE 9, 12 &15. I was familiar with the CADDIE 9 and did not want to adjust to use the “NEW CADDIE”.


How wrong can one be?  Ever since I started experiencing the latest version of CADDIE it is an absolute pleasure. If I get stuck, help is just a phone call away.


Thank You CADDIE for an excellent drawing programme.

With Caddie, changing drawings is now a small rather than a major part of my life

"Caddie is still the best CAD system on market, - I can vouch for that"

Paul Adams switches to Caddie and prefers it to AutoCAD for drawing his architectural plans, sections and elevations

‘I had been an AutoCAD user since 1996, but  found switching to Caddie really straightforward, and I now use it for all my drawing work.  My work consists mainly of drawing up existing surveys along with plans, sections and elevations and overall I find Caddie better for drawing.'
