Microsoft Visual C++ Redistributable for Visual Studio 2017 RC installs run-time components of Visual C++ libraries. These components are required to run C++ applications that are developed using Visual Studio 2017 RC and link dynamically to Visual C++ libraries. The packages can be used to run such applications on a computer even if it does not have Visual Studio 2017 RC installed. These packages also install run-time components of C Runtime (CRT), Standard C++, MFC, C++ AMP, and OpenMP libraries. **NOTE**: The installer replaces the existing installation of the Visual Studio 2015 Redistributable (i.e. performs an in-place upgrade).
