VuGen in LoadRunner 9.5 crashes when opening the parameter list
The following error message is displayed in the Vugen user interface when either accessing the parameter list or attempting to parameterize a value in a script:
vugen caused an EXCEPTION_ACCESS_VIOLATION in module MFC80.DLL.
A product that updates the mfc80.dll module (for example, SQL Server 2008) is installed in the affected machine. After this module is updated applications such as Vugen which are developed in Visual Studio 2005 will hit an access violation in the mfc80.dll module and then crash. The problem is due to a version incompatibility.
This problem is documented by Microsoft. The fix and further information about the problem is available at the following link:
