Additional information for troubleshooting startup errors:
- Install the latest service packs and hotfixes for your software. These updates can be found on www.autodesk.com under Services and Support > Data and Downloads after you select the appropriate product.
- Make sure that your computer meets all system requirements for the software you are running. You should refer to the Standalone Installation Guide on your product disk for specific system requirements. For AutoCAD-based software, you should refer to the tested and supported video card hardware and drivers list. The software cannot be expected to run, and will not be supported by Autodesk, on a system that does not meet these recommendations.
- Autodesk tests and supports AutoCAD-based software in basic, local Windows user profiles. Customizations or restrictions placed on the user profile may cause AutoCAD to function incorrectly or not at all. See the following solution for more information: Unable to run AutoCAD as a restricted user.
- Custom content, especially from previous releases of the program, may not be compatible. Remove custom search path content such as shortcuts, templates, menu/cui files and tool palette files.
- Software programs on your computer, such as antivirus, antispyware, or other security programs, may conflict with the startup behavior of your AutoCAD-based program. You can test for a software conflict by running the program in Windows Diagnostic Mode. For instructions on using the program in Windows Diagnostic Mode, see the following solution for more information: Starting AutoCAD® in Windows® diagnostic mode.
- If the program runs correctly in Windows Diagnostic Mode, it indicates a conflict with software on your machine. Contact your computer support professional for further assistance diagnosing and resolving conflicts with other software on the computer.
- If the program does not run correctly in Windows Diagnostic Mode, it indicates that other software on your computer is not likely the cause of the problem. At this point, it is strongly recommended that you repair or reinstall the software as described in the following solution: Recommended uninstall and reinstall procedures.
