What is VCRUNTIME140_1.dll?

The VCRUNTIME140_1.dll is a type of file called a DLL (Dynamic Link Libraries). It’s tied to Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017, and 2019. These libraries are what let apps made with Visual C++ run.

When an app needs VCRUNTIME140_1.dll, Windows will look in its own folders to find it. If it can’t or if the file’s broken, you’ll see the “VCRUNTIME140_1.dll was not found” error. This can cause the app (or game) to not start or crash midway. It can show different error messages like:

  • “VCRUNTIME140_1.dll is missing”
  • “The program can’t start because VCRUNTIME140_1.dll is missing from your computer.”
  • “The code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem.”
