PackagingResults:Error: Error Unknown Error

PLEASE HELP

I need urgent help packaging my UE4 project. I have been experiencing a Packaging results:Error:Error unknown Error.

I have no idea what it means or how to fix it. Can someone please help?

I have attached the output log here…link text

Well, it’s prob a bit late, but in your message log you have
“UATHelper: Packaging (Windows (64-bit)): UnrealBuildTool: ERROR: Windows SDK v8.1 must be installed in order to build this target.”
From what this looks like you needed to have updated your SDK

im getting the same error

Solucionado!!
