Le Microsoft Visual C++ Redistributable Package 64 bits installs the runtime components needed to run C++ applications built with Visual Studio 2015, 2017 or 2019.
Visual C++ 64-bit Redistributable Packages install runtime components of Visual C++ Libraries. These components are required to run C++ applications developed by Visual Studio that dynamically link to Visual C++ libraries. Even if Visual Studio is not installed on a computer, these packages can be used to run such applications. These packages install the C (CRT), Standard C++, MFC, C++ AMP, and OpenMP runtime components.
The installation of Microsoft Visual C++ Redistributable Packagee 2019, for example, will affect programs written using Visual C++ 2015 and 2017. Newer versions of files installed by the Visual C++ 2017 and 2019 Redistributables will not be overwritten by installing the Visual C++ 2015 Redistributable .
This differs from previous versions of Visual C++, which each had their own set of runtime files that were not shared with other versions.
Can I remove some of the Visual C++ redistributables I have on my computer?
It's best to keep them because most of them come with the applications you have installed on your computer and deleting them could cause the software or game to crash. Although you can try deleting older versions of the redistributables from your PC and see how things go - but that would require a lot of checking, so it's best to leave them alone. There's no need to go through all that trouble just to save a few MB on your computer.
Microsoft's strategy has changed dramatically in recent years. You no longer need to install Visual C++ 2017 Redistributable Packages if you have Visual C++ 2019 Redistributable installed, as older packages are now automatically supported.
