Re: Mass Effect msvcr100.dll Missing
The KB article in the "Additional Information" section says that the security update can only be installed if "Microsoft Visual C++ 2010 Service Pack 1" was installed before, and that was not the case as it seems.
- Press the Windows key and "i" at the same time > Apps
- Search for "Microsoft Visual C++ Redistributable"
- Make a screenshot of all installed Microsoft Visual C++ Redistributable packages and post it here.
Also create a DxDiag in text file format and post it with your next reply. You can do that with the "Choose file" button at the bottom right corner of the reply window.
