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 mfcm110u.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++ 2012

Microsoft still offers the Microsoft Visual C++ 2012 package (an older version, still required by many games). It restores mfcm110u.dll and the files of the same family.

Official Microsoft page of the Visual C++ packages

On the Microsoft page, download the Visual C++ 2012 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 2012 package › Modify › Repair.

The program can't start because mfcm110u.dll is missing.
Failed to load mfcm110u.dll
Error loading mfcm110u.dll. The specified module could not be found.

Why does this error occur?

Microsoft Visual C++ 2012 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 mfcm110u.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.
