Windows platform build and cook fail

After last update of launcher and/or installation of 4.12.4 engine version the editor stop to build for windows.
the error reported is equal to other people, I’ve tried to solve the issue following the solution provided but doesn’t work for me (I attached a txt file with the error reported [log.txt][1]).
Cook content for windows platform fail like build command with this message error:
Missing UE4Game binary.
You may have to build the UE4 project with your IDE. Alternatively, build using UnrealBuildTool with the commandline:
UE4Game

both error in both my engine version 4.11.2 and 4.12.5

Hey -

Looking at the error messages it appears you need to edit the installation of Visual Studio 2015. It mentions " 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." This can be done by choosing to modify the VS installation and then expanding Programming Languages and Visual C++ then checking the box for Common Tools. It may also help to check the box for Common Tools at the bottom of the features list.

Cheers
