windows 8.1, won't export out to win8

I just got a windows 8.1 computer. I downloaded the windows SDK from MSDN and got the free 2013 visual studio. When I try to export out the game to windows, I get this error. It will not compile. I can export out to android, windows 7 and such, just to windows 8.

The setting for windows store are as follows (although I have tried different settings). Type C++ SDK 8.0 dev build: off

I'm sure this is a simple thing. Thanks in advance.
