Have you looked through this post? http://answers.microsoft.com/en-us/windows/forum/winapps/cannot-install-windows-8-apps-error-0x80073cf9/97e793dc-4d46-44ab-a7ec-ec4a2b435304

Do you have the UAC enabled on your computer?

Answer 3

Hi,

This problem may be occurs when you mix development and deployed installs of the app.

Please see Prashant's blog entry Registration of the app failed. Another user has already installed a packaged version of this app. An unpackaged version cannot replace this… for more details and information on how to clean it up.

Best Wishes!
