Using AS3 to open Windows Metro Apps

Hello, I'd like to use NativeProcess to open up Windows Metro Apps but I'm not exactly sure how to do so. I've already located the .exe of the Windows Metro App I want to open however it refuses to open when I tried to. I assume that dropping it into my project and using NativeProcess there will not work either. If anyone could shed some light on this, that would be amazing! Thanks in advance!
