I was using the stand-alone version of Vugen used with Performance Center 9.5, and I noticed that it would crash every time I tried to create a parameter file. After some research, I found out it is because SQL Server 2008 was installed on the machine. Apparently, Vugen is doing something that conflicts with the mfc80.dll or mfc80u.dll file used by SQL Server 2008. This problem not only affects Vugen, but other applications as well.
