Q: I'm developing a Windows 8 application using Visual Studio 2012 but when I move between machines and recompile my application, the application will not launch and throws an "Unable to activate Windows Store app" error. What can I do?

A: I've seen this firsthand and multiple readers have emailed me about this issue. Below is the actual error.

The easiest solution to this problem is to delete the Debug folder from the bin folder of your project. This will resolve the problem.
