I recently installed Visual Studios 2015 and when I opened the Launcher to EpicGames I verified UE4 after that was completed I launched 4.9 and went to C++ Template and said that there was no compiler found. I did restart the launcher and verify again but nothing. So far I can’t find out how to fix this.
UE4 uses VS 2013;
The 2015 compiler and toolset is not fully supported by EpicGames for now, I believe, not sure.
Well… I guess I better reinstall to 2013. Thanks for reply 
4.10 will require VS2015;
Just saw the preview notes.
