Fail To Generate C++ Project files

An error occurred while trying to generate project files.

Running D:/Programs/Epic Games/UE_4.15/Engine/Binaries/DotNET/UnrealBuildTool.exe -projectfiles -project=“C:/Users/Дмитрий/Documents/Unreal Projects/MyProject3/MyProject3.uproject” -game -rocket -progress
Discovering modules, targets and source code for project…
ERROR: Windows SDK v8.1 must be installed in order to build this target.

Where to download it???

https://developer.microsoft.com/en-us/windows/downloads/windows-8-1-sdk

Thanks, forgot it !

If you use Visual Studio 2015 / 2017 you can select C++ for Games and then select the Unreal Launcher… this will ensure the correct Windows SDK is installed.
