These packages install run-time components of these libraries: C Runtime (CRT), Standard C++, MFC, C++ AMP, and OpenMP.įor example, installing the Visual C++ 2019 redistributable will affect programs built with Visual C++ 20 also. These package can be used to run such applications on a computer even if it does not have Visual Studio installed. These components are required to run C++ applications that are developed using Visual Studio and link dynamically to Visual C++ libraries.

The Visual C++ Redistributable Packages install run-time components of Visual C++ libraries. Microsoft Visual C++ Redistributable Package installs run-time components that are required to run C++ applications built using Visual Studio 2015, 2017, and 2019.
