Sorry what are these Redist packages?
The Redist packages are the things that allow certain applications (built on C++ I believe) to run.
So, if you are interested in installing them, they can be found in your game folder.
Just navigate to your game folder -> Click _Installer -> Click vc -> Click vc2013 -> Click Redist - > Then run both applications (x64 and x86).
They can also be found here if you need to download them: http://www.microsoft.com/en-us/download/details.aspx?id=40784
Edit: Thanks Woot, you beat me to it.
