AutoCAD MEP

[#1]

Recently installed AutoCAD MEP 2012 from a Deployment created on a Win 7 x64 Dell T3500

ran the Deployment successfully on multiple computers. 1 computer gives this message when switching Work Spaces

Fatal Error Unhandled e0434352h exception at fd83cacdh. AutoCAD crashes then it is launched again, and it opens fine with the selected workspace.

Have you tried a clean reinstall?  Is the UAC controls setr to "Never Notify"?  Is the user an Admin?  Did you launch the program for the first time as an Admin or right-click > "Run As Admin?"  Did you use the Microsoft utility to test .NET to see if it was running properly?  I think it's called the ".NET Verification Utility?"  Google will find it.  What's different about that one computer?

Wanted to follow up and see if the prior suggestions helped?
