Unhandled exception when using products based on AutoCAD 2010 or 2011

After installation, you were able to start the product, but when you tried to execute a command or select one of the UI items, the product crashed with the following error message:
Unhandled e0434f4dh exception at 7c81eb33h
This error is caused by Microsoft .NET Framework 3.5 Service Pack 1 not being installed properly.
You can download and install Microsoft .NET Framework 3.5 SP1 directly from the Microsoft website:
Microsoft .NET Framework 3.5 Service Pack 1
Once you have installed .NET Framework 3.5 SP1, the product will work as expected.
