Thanks!

To clarify, are you getting the "Windows.Foundation.UniversalApiContract"
crash? Or are you talking about the incorrect version check once the app
starts? Could you confirm the windows version and what the error is.

I did some debugging, it seems there is an issue on this line:

Here, nt->OptionalHeader.MajorOperatingSystemVersion is 4, so it reverts to the
default current version which is Windows 8.0.
