How do I know which Visual C++ redistributables I have installed?

Microsoft Visual C++ Redistributables are collections of standard functionality that many applications use. Instead of each application having to duplicate the code, Microsoft has compiled them into libraries that the applications can use. Most of the time when you install a new application, the installation will include the redistributables it needs. But not all applications do this. And that’s one occasion when you have to check which of them you have and which you need to install.

How to find out if I have them

Open the Control Panel and go to Programs and Features.

You might have to click on the Programs category to find it.

Scroll down until you see Microsoft Visual C++…

And of course, if you don’t see any of them, they aren’t installed on your machine.
