What is Microsoft Visual C++ Redistributable?

Microsoft Visual C++ Redistributable (MSVCR) is a package offered by Microsoft for programs developed using Visual Studio. It contains C and C++ runtime libraries. It is basically plug-and-play on Windows platform, meaning, download the required Visual C++ version number requested by the program and install it to start working. If the program built uses C or C++ libraries, then the corresponding Visual C++ package is required to run the program. The architecture of Visual C++ must match the application's target architecture.

Which Visual C++ Redistributable is needed?

There are multiple versions of Visual C++ available, and you can download and install specific versions according to your computer architecture. The packages are available for both 32-bit and 64-bit architecture. If you have a x64 (64-bit) operating system (OS), then you can install both x64 and x86 (32-bit) on your Windows platform. However, for x86 operating systems, you can only download and install x86 versions. Here is a list of all available versions for both x86 and x64 OS: Latest Supported MSVCR for Visual Studio.
