Unknown Error While Packaging To Windows

5 seconds after I start the packaging it gives me an error

PackagingResults:Error: Error Unknown Error

Full log here
Care to help?

Thanks a lot!

EDIT: Reduced the log with just the Packing attempt.

Also, there is a section on the log in portuguese for some reason, it says:

“J� foi adicionado um item com a mesma chave.”

Translation : “An item with the same key has already been added.”

So it goes like this

MainFrameActions: Packaging (Windows (64-bit)): Program.Main: ERROR: AutomationTool terminated with exception:
MainFrameActions: Packaging (Windows (64-bit)): Program.Main: ERROR: Exception in mscorlib: An item with the same key has already been added.

Nevermind, found the answer here:
