GenerateProjectFile requires Windows SDK 8.0 when 8.1 is installed

I am failing to get GenerateProjectFile running.

At my first attempt to launch it it requested Windows SDK 8.1. I installed it and ran the program again. Now it asked for Visual Studio 13. I had VS 12 installed so I went into the BuildProject.cs (can’t remember the name accurately) and changed the compiler to VS 12. Now when I run GenerateProjectFile, it requires Windows SDK 8.0! I have no idea how to solve it as I already tried restarting/reinstalling SDK etc. I can’t find the 8.0 installer in the net and I don’t understand why the bat file requires it when I have the 8.1 one?

Maybe VS2012 is not compatible with SDK8.1, Single google search

Also, why dont you just install VS2013?

Because I have a tone of work in VS12 and I am not ready to switch right now. Is there a way to download 8.0 SDK somewhere?
Edit: I guess I found it. Thanks for the reply!
