Fatal error RC1015 and C1083 'windows.h'

Greetings, Unreal wizards! I hope you can help me here.

I’m using U4 9.2 on two team projects (with revision control by Perforce).

When I hit compile on both projects, I get these errors :

fatal error RC1015 and C1083 : Cannot open include file: 'windows.h’

Following the advice of programmers on my team, I uninstalled both Unreal and Visual Studio.

Then I installed VS2013 first and U4 9.2 second.

But it didn’t change anything, I get the same errors. What does this mean? How can I make it work?

PLEASE HELP! ^^ Thx

In case of UE4 is cross-platform engine you can’t use windows.h. I mean even if you were able to include windows.h then you will have big problems when compiling this game for PS or XBox or even Android.
Avoid using platform-specified libraries and headers, engine already have libraries to work with different platforms using same methods.
If you didn’t change anything, then someone figured out the way to enable windows.h or another header containing this one (sadly it is possible) what is not covered by source control. Basically you need to ask to not to use it and replace with something else.
I can say what you can use to replace if you find anything.

hey i have got the same problem and I can not fix that, would you mind to give more details?
