When you try to start System Information, you receive the following error messages:
A required .DLL file, C:\WINDOWS\SYSTEM\MFC40.DLL, was not found.
Cannot find the file 'C:\Program Files\CommonFiles \Microsoft Shared\MSINFO\MSINFO32.EXE' or one of its components). Make sure the path and filename are correct and that all required libraries are available.
