Can't Conpile: unreal tournament 4 editor

Hi,

I’m almost finished with my map but everytime I try to compile it gives me an c++ error message.

Here’s what it looks like:

Its a clean install of of unreal tournament editor, I have also installed the UT game, all via the epic games launcher.

If anyone knows what causes this issue, I would greatly appreciate it.

Thanks in advance,
Chris
