Civil 3D 2011: Unhandled Access Violation Error Reading 0x0000 Exception at 8c4513h

Another mysterious Fatal Error/Unhandled problem solved!

When starting Civil 3D 2011, you get this error:

Unhandled Access Violation Error Reading 0x0000 Exception at 8c4513h.

In the Command Prompt, Civil 3D 2011 provides the following clue:

The symptom is one user account Civil 3D will startup properly but in another user account on the same computer, Civil 3D will not startup properly.

The solution is to copy the ContextualTabSelectorRules.dll from the working profile to the problematic profile.

Thanks to Elias B. Trad and Avto Chachava for this tip.
