Fix: Missing mfc100.dll library for Windows 7

Today I downloaded a program (CamStudio) and it installed normally in my Windows 7. Then I tried to launch it and I got this error message:

The program can’t start beacuse mfc100.dll is missing from your computer. Try reinstalling the program to fix this problem.

missing mfc100

As you can imagine, reinstalling the program didn’t help. So I searched the internet for the file, downloaded the missing.dll file and copied the new one into my Windows.

The destination folder for the .dll file in my case was: c:\windows\sysWOW64

Strangely enough, the folder already contained a copy of the .dll file, soy I had to overwrite it with the new copy.

The fix took effect immediately and I could launch my CamStudio program without problems and without the need of a system restart. Though restarting is always a good idea after making changes in Windows systems.

Here’s a link to a copy of the mfc100.dll (it’s inside  a .zip file): Click here for the mfc100.dll file
