When launching, opening a file, or clicking a command or menu in AutoCAD 2012, 2013, 2014 on Windows 8, 8.1, or 10 system, a fatal error is encountered and the program crashes, such as the following:
Unhandled Access Violation Reading 0x0000 Exception at db16f7adh
Additionally, it is possible to see this same behaviour can be seen on Windows 7 systems.
Causes:
The .NET Framework 4.7 has been installed on the system.
Note: Windows 10 is not a supported platform for AutoCAD 2014 an older.
Solution:
- Roll back any recent Windows updates, particularly for .NET Framework 4.7 (see Autodesk products not working after installing .NET Framework 4.7).
- Use Windows System Restore to revert to a point before the crashes started. Declining future Windows updates should keep your AutoCAD programs running, although this is not recommended. Not updating a Windows system could put you at risk by missing out on installing security patches and other important updates from Microsoft.
- Upgrade to a newer version of AutoCAD, although, it is possible that .NET Framework 4.7 can still be a conflicting factor.
- Run the product on a supported version of Windows and avoid installing .NET Framework 4.7. Here are links to the system requirements for AutoCAD versions 2012, 2013, and 2014:
