Which version should you choose? The one that matches the program showing the error, not Windows: a 32-bit game or program needs the 32-bit DLL, even on 64-bit Windows. If in doubt, try the 64-bit version first, then the 32-bit one if the error persists or becomes “0xc000007b”.

Then:

Extract mfcm120.dll from the zip file and copy it to the folder of the program showing the error (where its .exe file is).
Still getting the error? Copy it to C:\Windows\System32 (64-bit DLL) or C:\Windows\SysWOW64 (32-bit DLL on 64-bit Windows), then restart.

Reinstall Microsoft Visual C++ 2013

Microsoft still offers the Microsoft Visual C++ 2013 package (an older version, still required by many games). It restores mfcm120.dll and the files of the same family.

Official Microsoft page of the Visual C++ packages

On the Microsoft page, download the Visual C++ 2013 package in its x86 version, and also x64 if your Windows is 64-bit.
Run them, then restart your computer. Already installed? Settings › Apps › the 2013 package › Modify › Repair.

Error messages related to mfcm120.dll

The program can't start because mfcm120.dll is missing.
Failed to load mfcm120.dll
Error loading mfcm120.dll. The specified module could not be found.

Why does this error occur?

Microsoft Visual C++ 2013 is not installed: new computer, reinstalled Windows, or a program that does not install its own prerequisites.
The file was deleted or damaged: another program was uninstalled, an overly aggressive cleanup, an antivirus.
Wrong architecture: a 32-bit program cannot use the 64-bit version of the DLL, and vice versa.

Frequently asked questions

Is mfcm120.dll a virus?

No: it is a legitimate Microsoft file. Only be wary of a copy found outside C:\Windows or a program’s folder; you can compare its SHA-256 fingerprint with the one shown on this page.

Should I install the 32-bit or the 64-bit version?

On 64-bit Windows, install both: a 32-bit game needs the x86 version, even on 64-bit Windows. On 32-bit Windows, only the x86 version can be installed.
