So… I did download myself the unreal engine to try it out.
But after i did install it, i did start it up and found this error on the bottom of the window:
That wonderts me, i do not have visual studio 2013 installed, but an (in my opinion) better version !
As you can see here:
To my knowledge, this installed the full load of C++ compilers as VS2013 and im not willingly to go throu the whole install process (that takes 4->6 hours on my system) again, only to install VS2013.
So the final question is, is it possible to make UE accept my VS2015RC as an valid compiler ?
