Cause
The Microsoft Foundation Class libraries are normally installed as standard on a PC.
But most applications these days are .NET.
It may be that Windows 7 does not install all the MFC libraries as standard.
Resolution
Option 1:
If the error shown below in Fig1. is displayed, you may be able to correct the problem simply by downloading this zipped file which contains both MFC71.dll and mfc71u.dll.
Copy these to your "C:\Windows\System32" directory.
Fig 1.
DLL files also available here.
Option 2:
The libraries can be installed by installing the Microsoft Visual C++ 2005 redistributable library which can be obtained free of charge from Microsoft. Copies are also available as a direct download.
