I don’t have any other version of Visual Studio than Community 2015. I don’t want to compile it with VS 2013, VS 2015 is supported now so i am trying to compile it with it. VS 2015 is on my SSD, the UE4 is on my HDD(they are on different partitions). The path of UE4 is D:\UnrealEngine, the path of VS is C:\Program Files (x86)\Microsoft Visual Studio 14.0. I don’t have any special symbols in the paths like & so the first suggestion is not an option. Also i don’t have second declaration for system 32, edited C:\Windows\system32; to C:\Windows\system32; but the result is the same, so neither of you suggestions worked.
