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.

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 

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, install your 64bit AutoCAD products as normal then use the Longbow Converter to fix all 64bit AutoCAD 2008 thru 2013 Windows 8 issues

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.

AutoCAD “There was a problem sending the command to the program”

If you are seeing the message “There was a problem sending the command to the program” when you double click a DWG file from Windows Explorer, then the solution is to follow the instructions listed for your AutoCAD version below:

If you do not see your version of AutoCAD listed, or you are not an AutoCAD user, leave me a comment below and I’ll check it out for you.

AutoCAD File->Save or File->Open Crash…

If are experiencing crashing problems using the File->Open or File->Save dialog inside of AutoCAD (or any other Autodesk product), there are a few items that can cause this:

  1. New HP Machine If you have recently purchased a new HP computer or you have an HP computer for which you have recently carried out an HP update on Windows 10, Windows 7, Windows 8 or Windows 8.1…Check if you have any of these applications installed:
    • HP Trust Center
    • HP Client Security Manager

      If so, uninstall them and reboot. We recommend you find an alternative as they cause this issue.

  2. For AutoCAD versions >= 2008, you can try disabling the InfoCenter toolbar at the top right of AutoCAD.
    1. If you know LISP, this code will work for all versions of AutoCAD 2008 or higher
      1. add this code to the end of your acad.lsp (vl-registry-write (strcat “HKEY_LOCAL_MACHINE\\” (vlax-product-key)”\\Applications\\InfoCenterAcConn”) “LOADCTRLS” 0)
    2. If you do not know LISP
      1. Start Regedit.exe
      2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\AutoCAD\<Release.Number>\ACAD-<VerticalCode>:<LanguageCode>\Applications\InfoCenterAcConn 
      3. Set the LoadCtrls value to 0
      4. To turn it back on, simply set LoadCtrls value to 76
  3. Remove all USB devices – older versions of AutoCAD don’t understand what a Samsung Phone is, and this can cause crashes.
  4. If you have been opening DWG files from your USB drive, try re-connecting the drive…
  5. The latest Windows Operating systems (Windows 10, Windows 7, Windows 8 and Windows 8.1) correctly use strict permission settings for your personal files (Documents folder etc). The problem is that your older version of AutoCAD does not understand these new permission settings, and this can cause AutoCAD to crash. As a quick test, copy the DWG files that always crash when you save to a USB drive, then create a new folder called c:\MyDwgs, now copy the files from your USB to the c:\MyDwgs folder. Finally, try AutoCAD with the DWG files in c:\MyDwgs – is AutoCAD working now? If so, you can either leave your DWG files in that folder, or you’ll need to relax the permissions on your DWG folder to allow access to AutoCAD.
  6. MSN Plugin – if you see MSN as an entry in your Windows Explorer, uninstall MSN – AutoCAD doesn’t like this.
  7. For versions of AutoCAD >= 2000i here’s a quick fix to bypass the problem (although hard to remember each time) – on starting AutoCAD, type “Options” at the command line, select the ‘Files’ tab, click ‘Browse’, then simply click cancel. Now cancel out of the Options dialog altogether. Try your File->Open… Does it work? If so, you should now be good until the next time you start AutoCAD.
  8. If you have a non-HP machine that is giving you this issue or (2) didn’t work for you, please record below in the comments section:
    1. What computer make you are running
    2. What specific Windows version you are running
    3. What exact version of AutoCAD you are running (e.g. AutoCAD Architecture 2008 32bit)
    4. What AutoCAD service packs (if any) you have applied
    5. What anti-virus software you are running. We’ll see if we can solve this for you…
  9. Check out this page Interactions with the AutoCAD Ribbon crashes AutoCAD on Windows 10
  10. If all this fails, you can of course set FILEDIA = 0 at the command line to turn off the File Dialog User Interface
