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.

UnrealBuildTool Exception: ERROR: Windows SDK v8.1 must be installed in order to build this target.
Make sure you specifically selected
the “C++” options in the Visual
Studio 2015 installer. It’s a
separate option from the Visual
Studio IDE itself.
Ensure that you either have Windows
SDK 8.1 installed or you have
Windows SDK 10 installed with the
“UseWindowsSDK10” variable set tot
true in unreal build tool windows CS
file.
Ensure that you generate the project
files with “GenerateProjectFiles.bat
-2015” command.
Give those a try and see if any of them solve the problem.
If it’s Visual Studio Community 2015, it’s the version you want. I can’t remember if it comes with Windows SDK, but if it builds, that means you already have it.
