Hi .

this is the error you have . “Visual C++ 2015 toolchain does not appear to be correctly installed. Please verify that “Common Tools for Visual C++ 2015” was selected when installing Visual Studio 2015”

you must select common tools for visual c++ 2015 when you want install visual studio.

try to reinstall visual studio with common tools selected at first

Thx for all! I added C++ to my VC & i deleted some C++ scripts from DefaultEngine.ini (“Failed to find value when parsing E:\Epic Games\Projects\Between\Config\DefaultEngine.ini, line 12”) and than i saw UE4Game.pdb error. Next i installed Editor Symbols for debugging and now i Launch my Game very well.
