Ue4 rc1015 error compiling

Hi everyone!

I wanted to start programming with Unreal Engine in C++. Because I previously programmed in C++, I already had everything set up.
But then, I tried to create a C++ blank project in the Installer and it said “fatal error RC1015 occured: cannot open included file “windows.h””.
So I looked at the forums and tried every previous solution: Changing username to just english characters, checking “inherit from parent” in VS13, manually adding windows.h, reinstalling everything in a good order.
But nothing worked for me. Still the same error. The Blueprint thing works for me though, but I want to code everything and really learn C++.
So if anyone knows a solution, please tell me!

Thanks for any help!
