C++ error C4599

Everytime I try to compile I get the error: [SPOILER]
"Info C:\Users\Birger\Dropbox\Projects\Projs\Intermediate\Build\Win64\UE4Editor\Inc\FPSTemplate\FPSTemplate.generated.cpp: error C4599: ‘/IC:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\INCLUDE’: command line argument number 252 does not match precompiled headerC:\Users\Birger\Dropbox\Projects\Projs\Intermediate\Build\Win64\UE4Editor\Development\FPSTemplate\Module.FPSTemplate.cpp: error C4599: ‘/IC:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\INCLUDE’: command line argument number 252 does not match precompiled header
"[/SPOILER]
I have no idea why this happens and i wounder if it even is the reason behind me not beign able to compile.
The reason why I am doubtful is because in the log it is not marked as an error, as you can see in the screenshot below.

I am really new to C++ and have no idea why this is, please help me.
If you need any scripts just ask!
