Making the Calcomp Digitizer work in old versions of AutoCAD

Some users have experienced issues where their Calcomp Digitizer works just fine in new versions of AutoCAD (like AutoCAD 2009, but doesn’t work on older versions of AutoCAD (like AutoCAD 2000) even though both versions are installed on the same computer.

We have reports that simply disabling the Windows User Access Control  (UAC) seems to fix this issue!

AutoCAD 2000 Proxy dialog warnings

If you are seeing a message like this while opening DWG files using AutoCAD 2000…

The last command created proxy objects and proxy entities to represent original objects and entities whose parent ARX application(s) are currently not loaded.

It’s because you are missing the AutoCAD 2000 service packs. You need to install AutoCAD 2000 sp1 and then AutoCAD 2000 sp2, as described half way down on this page Installing AutoCAD 2000 on Windows 7, Windows 8 and Windows 10

Opening AutoCAD DWG file gives “Drawing File was created by an incompatible version” message

If you are trying to open a DWG file with AutoCAD and you get the message “Drawing File was created by an incompatible version” it’s because somewhere along the line your AutoCAD DWG files were saved with a newer version of AutoCAD.

All is not lost, you can make them open again in your version of AutoCAD, you just need to download the free DWGTrueView App from Autodesk – http://www.autodesk.com/products/dwg/viewers

Once installed, start DWGTrueview and open the DWG file in question, then save as making sure to select the lowest DWG file version that matches your version of AutoCAD.

    1. Next, click the “Run Old Installer” button, it will start processing.
    2. When the Converter asks if this is a plugin to AutoCAD, click “Yes”
    3. Read and understand all prompts as they appear, before pressing OK to dismiss them.
    4. Now, I know it’s unheard of these days, but at this point expect to wait at least 45 minutes for your AutoSolids 2K setup.exe program to appear.
    1. Once the AutoSolids 2K setup starts, stop and read the next step…
      1. Note: If your AutoSolids 2K setup does not start after 45 minutes, read the Troubleshooting section below.
  4. In the setup program, navigate through each setup dialog as normal, except when you get to the installation folder input dialog, **it’s vitally important to make sure you install to c:\acad2000 (not C:\Program Files\AutoSolids A2K as normally prompted)** – see image…

Upgrading your working AutoCAD to a new Microsoft Windows version (like Windows 10)

Here are some useful notes on what to do with your AutoCAD when upgrading your Windows version, including upgrading from Windows XP, Windows Vista, Windows 7, Windows 8, Windows 8.1 to Windows 10…

Windows XP and Windows Vista AutoCAD users upgrading to Windows 10

For those of you who are still running AutoCAD on Windows XP and want to upgrade to Windows 10, you will need to first install Windows 10, then you need the Longbow Converter tool to install your AutoCAD – click on the version of AutoCAD you have (it explains all that you need to do) : AutoCAD R14 AutoCAD 2000 AutoCAD 2000i AutoCAD 2002 AutoCAD 2004 AutoCAD 2005 AutoCAD 2006 AutoCAD 2007 AutoCAD 2008 32bit AutoCAD 2009 32bit AutoCAD 2010 32bit AutoCAD 2011 32bit AutoCAD 2012 32bit AutoCAD 2013 32bit AutoCAD 2014 32bit

If you can’t find your version listed, use the “Search” at the top left of this page

Windows 7, Windows 8 and Windows 8.1 AutoCAD users upgrading to Windows 10

If you have an existing working installation of AutoCAD running on Windows 7, Windows 8 or Windows 8.1 and are thinking about upgrading your currently Windows version to a newer Windows version – I have some advise for you: be cautious! You see, with every new version of Windows (and its updates) comes a new set of compatibility issues, registry changes, file system security updates, internet browser updates, etc which if you blindly upgrade will most likely render your working AutoCAD useless.

With that said, it is totally possible to upgrade to the newest version of Windows and bring your old AutoCAD with you (that’s the point of our Longbow Converter solution) just be sure to do of a couple of things…

  1. First, *you must* have the latest version of the Longbow Converter (see below); we are constantly updating this solution to solve the ever changing world of Windows and their security updates.
  2. Second, find your particular Windows upgrade scenario below and follow the instructions ***precisely*** as documented!.
All AutoCAD users running Windows 7, Windows 8 and Windows 8.1 upgrading to Windows 10

Our Longbow Converter tool fully supports Windows 10. We specifically tested the Windows 10 64bit Enterprise and Windows 10 32bit Education versions with a combination of around 850 different install combinations.

Here’s what you need to do in order to upgrade to Windows 10:

  1. Finally, reinstall your AutoCAD as you did previously using the instructions on this blog (if your specific instructions are missing or not up to date with Windows 10, please let us know by clicking on this link and we’ll get it written up for you)
  2. Obtain the latest Longbow Converter supporting Windows 10 here
  3. Upgrade to Windows 10
  4. Make sure you uninstall any previously installed Longbow Converter versions.
  5. Make sure you uninstall all AutoCAD products before doing the upgrade to Windows 10, you *must* do this otherwise your AutoCAD may never startup again and you will have to wipe your computer to fix it.
  6. What happens if you already upgraded to Windows 10 with your existing AutoCAD installation – most likely your AutoCAD will not run, nor will you be able to repair it. The best thing to get your AutoCAD running again is to carry out a Windows Reset.
32bit AutoCAD users of versions 2002 thru 2013 and running or Windows 7 upgrading to Windows 8.1

If you have a working Windows 7 machine and you are thinking to upgrade to Windows 8.1 best just stay where you are. Better to upgrade to Windows 10, aside from being a free upgrade, it seems to be a much better platform too.

With that said, if you must upgrade your working Windows 7 system to Windows 8.1, then it is of course possible using our Longbow Converter tool – you ***must*** first uninstall all AutoCAD products before doing the upgrade. Once Windows 8.1 has been installed, just use the Longbow Converter to re-install your 32bit AutoCAD software as before.

  • What happens if you already upgraded to Windows 8.1 with your existing AutoCAD installation – most likely your AutoCAD will not run, nor will you be able to repair it. The best thing to get your AutoCAD running again is to carry out a Windows Reset.
64bit AutoCAD users of versions 2008 thru 2013 upgrading from Windows 7 to Windows 8.1

Clean install of Windows 8.1 – installing AutoCAD 32bit 

If you are doing a clean install of Windows 8.1, once Windows 8.1 has been installed, simply use the Longbow Converter to re-install your 32bit AutoCAD software as required.

Clean install of Windows 8.1 – installing AutoCAD 64bit 

If you are doing a clean install of Windows 8.1, once Windows 8 has been installed, install your 64bit AutoCAD products as normal then use the Longbow Converter to fix all 64bit AutoCAD 2008 thru 2013 Windows 8 issues

  • What happens if you already upgraded to Windows 10 with your existing AutoCAD installation – most likely your AutoCAD will not run, nor will you be able to repair it. The best thing to get your AutoCAD running again is to carry out a Windows Reset.
