Compile failed

Hi there,

New to UE, when i try to start my first project i get this error:

Running C:/Program Files/Epic Games/UE_4.16/Engine/Binaries/DotNET/UnrealBuildTool.exe UnrealOne Development Win64 -project=“D:/Unreal projects/UnrealOne/UnrealOne.uproject” -editorrecompile -progress -NoHotReloadFromIDE

ERROR: Windows SDK v8.1 must be installed in order to build this target.

I already installed SDK V8.1 , didnt seem to work.

Then i try to “Open with visual studio” i get:
Could not edit the code editing IDE D:/Unreal Projects/UnrealOne/UnrealOne.sln could not be found

Then i try to open it again manualy, i get:
Followind modules are bissing or built with different engine version:
would you like to rebuild?
Yes>>>>UnrealOne could not be compiled. Try rebuilding from source manually.

I already tried Generate visual studio project files, didnt help either.

soooo… out of options, halp
