Microsoft Visual C++ Redistributable is a runtime library for running applications that Microsoft developers develop in Visual C++ language (Using the Microsoft Visual Studio development environment).
There are many Microsoft Redistributable packages installed on your system. You can view them by going to the Control Panel/Programs/Apps and Features. And in the list of installed programs, you will see that there is more than one package of Microsoft Visual C++ Redistributable.
VC++ Redistributable is just like Java Runtime Environment and .NET Framework. You need to install JRE to run programs developed in Java and .NET Framework to run apps built with .NET Framework.
Finding Visual C++ Redistributable in Installed Programs
When you create certain Apps or Programs using Visual C++, the Redistributable packages are installed automatically. Some developers pre-package the runtime libraries inside their software setups. Or you can download them manually. I am providing you with the Links to download the Redistributable packages.
If you are using the same version of Microsoft Visual C++ to create multiple Apps, then all the Apps created with the same version of Microsoft Visual C++ needs one Redistributable package for all.
