MSVCR120.dll was not found, what it means and how to fix it

MSVCR120.dll is the C runtime library from Microsoft's Visual C++ 2013 package. Programs built with Visual Studio 2013 need it to start, and the usual "was not found" message means the 2013 redistributable was never installed on this PC, or an uninstall or cleaner removed part of it.

The fix, in order

  1. Install the Visual C++ Redistributable for Visual Studio 2013 from Microsoft, both vcredist_x64.exe and vcredist_x86.exe. A 32-bit program needs the x86 package even on a 64-bit PC. Restart the PC when done.
  2. Already installed? Repair it instead. Settings → Apps → each "Microsoft Visual C++ 2013 Redistributable" → Modify → Repair, for both the x86 and x64 entries.
  3. Reinstall or verify the program itself. For Steam games: right-click → Properties → Installed Files → Verify integrity of game files. A damaged program folder can keep failing next to a healthy runtime.
  4. Run Windows Update, then restart. Servicing updates sometimes replace runtime files, and a pending reboot can leave mismatched versions in place.
Do not download MSVCR120.dll by itself. DLL download sites offer single files of random versions, sometimes bundled with installers nobody asked for. The DLL belongs to a matched set installed by Microsoft's package, that package is the fix, and it is free.

If it still happens

Look inside the failing program's folder for its own copy of MSVCR120.dll. Some programs ship a private copy, and if that copy is older or damaged it overrides the healthy system one. Rename it (add .bak) so the program falls back to the system DLL, then relaunch. If only one program fails while others work, that program is damaged, and a clean reinstall is the remaining move.

Common questions

Is MSVCR120.dll part of Windows? No. It ships with the Visual C++ 2013 redistributable, which many programs install alongside themselves. On a PC where nothing has installed it yet, it legitimately does not exist until the package is run.

Will the newer 2015-2022 redistributable fix it? No. Each Visual C++ generation is separate, and the 2015-2022 package does not contain the 2013 files. A program that asks for MSVCR120.dll needs the 2013 package specifically, installed alongside any newer ones.
