If it is missing or damaged, Windows displays for example: “The program can't start because vcomp120d.dll is missing from your computer.” Two methods can fix the error, below.

Method 1 · quick · about 1 minute

Download only vcomp120d.dll

Ideal if only this file is reported missing: you replace a single file, without reinstalling anything.

Then:

Extract vcomp120d.dll from the zip file and copy it to the folder of the program showing the error (where its .exe file is).

Method 2 · complete · for developers

Install or repair Visual Studio

Debug files (ending in “d”) are not redistributable: Microsoft only provides them with Visual Studio. A program that asks for them was compiled in debug mode.

If you use the program: ask its publisher for a “Release” (non-debug) version.
If you are a developer: install or repair Visual Studio with the “Desktop development with C++” workload.

Error messages related to vcomp120d.dll

The program can't start because vcomp120d.dll is missing.
Failed to load vcomp120d.dll
Error loading vcomp120d.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 vcomp120d.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.
