One of our client's AutoCAD 2013 installations crashes randomly when opening random drawings. The software itself appears to be running stable. This (or similar) is the usual error:
It's installed on a Windows 7 Ultimate x64 Edition Service Pack 1 machine, 6 GB RAM, Intel Xeon E5540 CPU, nVidia Quadro FX 580.
I'm not an AutoCAD user myself, but based on the client's report, drawings he had opened before are now crashing the software. Sometimes, however, it works fine. There are no special plug-ins in use. Most of the native add-ons are installed. Some drawings were ported from Civil3D, but are not an issue usually, either.
Steps I have already tried to resolve this problem (partially based on Autodesk support):
1) Install AutoCAD 2013 compatible graphics drivers.
2) Apply a VB hotfix said to resolve issues.
3) Exclude Autodesk directory from Antivirus program.
Ideally I would not like to have to suggest a complete uninstall/reinstall. Any suggestions?
