RunUAT.bat ERROR: AutomationTool was unable to run successfully

Hey. I’m trying to build my game and I’m gettings an error. I tried most sollutions but nothing helps. It did build fine some time ago and i have no idea why I’am gettings this error.
Here’s my error log: https://dl.dropboxusercontent.com/u/80450760/Code.txt

Hey DoubleDoor,

Do you have a version of Visual Studio on your machine? The automation error is stating, “You are attempting to compile on a machine that does not have a supported compiler!”

This is an indication to me that you do not have the required application to compile code within your project.

Let me know if you have further questions.

Cheers,
