This app failed to launch because of an issue with its license
visual-studio-2012, windows-store-apps
Solution
Well, I got it working by deleting the main project's 'bin' and 'obj' folders. Cleaning and Rebuilding wasn't enough. Hope this answer saves someone else the few minutes of confusion I just experienced.
Problem
I'm happily in the middle of coding then I try to launch my app in debug mode but I get this error message. Unable to activate Windows Store app This app failed to launch because of an issue with its license The app was launching fine a few minutes earlier so this came as a surprise. I tried restarting Visual Studio but doing so did not help. I got the annoying "renew your developer license" dialog yesterday I think. It had renewed without issue. How do I make this error message go away so i can debug my app?
