When I open up AutoCAD 2008 I receive the following error:
FATAL ERROR: Unhandled Access Violation Reading 0x0034 Exception at 7c901010h

This is running on XP Pro.  I installed this application as the local administrator, set the permission to modify for the user and this is the error we receive.  Any help would be much appreciated.  Thanks!

    Did you updated your video card driver when you installed 2008?

    Yes I updated the video card.  I set the configuration to hardware acceleration also.

    Was there a previous version of Autocad on this computer before?
    If so, i might be that it wasn't properly uninstalled prior to installing 2008. Everywhere i look at is pointing to a re-install of 2008 to fix many, many crashing issues.

    From Autodesk's forums:


    To remove a program that will not uninstall from the Control Panel, please use the Windows Installer Cleanup Utility to remove AutoCAD. This tool can be downloaded from

    Once AutoCAD is uninstalled, please remove any remaining files and registry keys as follows:
    1. In Windows Explorer, delete the installation folder for AutoCAD 2008 (by default this is C:\Program Files\AutoCAD 2008)
    2. Log on to the workstation as a member of the local Administrators group.
    3. On the Start menu (Windows), click Run.
    4. In the Run dialog box, enter regedit in the Open box and click OK to start the Registry Editor.
    5. In the the Registry Editor, locate the following subkeys and delete them:

    o HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R17.2
    o HKEY_LOCAL_MACHINE\Software\Autodesk\AutoCAD\R17.2

    6. Exit the Registry Editor.
    7. Reboot the computer.

    And / or

    1) Delete all files and directories from the User Temp folder. Use %TEMP% from Windows Explorer or go to C:\Documents and Settings\UserAccountName\Local Settings\Temp\ for the Windows user accounts on the machine.

    2) Clean your Internet browser's temp files cache.
    Internet Explorer
    On the Internet Explorer Tools menu, click Internet Options. The Internet Options box should open to the General tab.
    On the General tab, in the Temporary Internet Files section, click the Delete Files button. This will delete all the files that are currently stored in your cache.

    Mozilla Firefox
    On the Firefox Tools menu, click Options.
    In the Privacy section of Options, click the Clear button. This will delete all the files that are currently stored in your cache.

    3) install the latest driver for your video card. You will find the version of the driver that is certified to run with our product at Please download and install the one for your card.

    4) Follow once again this solution to clean remove the software then,

    5) Reinstall using this solution

    6) Do not migrate any settings from a previouse version of AutoCAD, do not migrate your cui files at this point.

    Good luck! :o/

    I think you are right here.  There was a previous version on the PC.  I did an uninstall, but I never went removed anything from the registry.  I think I'll install a fresh copy and will go from there.  I think you are right. Thanks for your help.
