Hmm… I always get the “error : Visual Studio 2012, 2013 or 2015 must be installed in order to build this target.” when I compile UE4 (editor). I also have “ignored” icon on most of the items in VS. I compiled everything with -2015 argument and VS tells me in console that for UE4 subproject it uses:
"..\..\Build\BatchFiles\Build.bat UE4Editor Win64 Development -waitmutex -2015"
What can I do about that?
EDIT: When I try to compile “ignored” subproject I get errors from this topic.
