What Is This Error? This error message appears when you try to install or run a software application (often a game, CAD software, or developer tool) that was compiled using Microsoft Visual C++ 2019 . The application requires specific runtime files (DLLs like vcruntime140.dll , msvcp140.dll ) to function. When the system detects that the x64 version of the redistributable is missing, it blocks the installation or launch.
In almost all cases, simply downloading and installing the official x64 redistributable solves the problem. The error is one of the most common “missing runtime” issues on Windows, and Microsoft provides an easy fix.
