Error while running GenerateProjectFiles

Hi!
I wanted to compile the Nvidia version of the engine, but I got stuck at GeneratingProjectFiles.bat. When I run it, it says something about missing .NET Framework 4 and mismatch between processor architect and MSIL. After that,it says Windows SDK 8.1 is missing. My processor is an AMD FX8150, if it matters.
Here’s a picture of command prompt:

Edit: After installing Windows SDK, I could open the project files with Visual Studio 2013, but it says it’s incompatible with these files…

Bump
Can anyone help with this?
