I downloaded and ran GPA's Analyze Application option and it works every time for the sample app. On the first try, I was able to get it to work for Windows Store apps as well. However, now when I run it on any Windows Store app, it always fails with: "Intel GPA Monitor failed to launch the application: Failed to launch Windows 8 Store application" I didn't change my system at all in between the success and failures. Tried restarting, etc. but no change. What could be going on? Is the Windows 8 Store monitoring known to be buggy?
