I upgraded from Windows 7 Pro to Windows 8 Consumer Preview and the Metro apps won't start when clicked. The app appears to start, the screen fills up with a green background with the app logo centered, but nothing happens afterwards. After searching for a similar issue on the web, I've found a few posts regarding a similar issue in the developer preview and have already verified that my resolution is large enough - 1440x900, and that UAC is properly enabled.

The Windows Event viewer shows only one anormal event - DCOM Event ID 10010 (Service failed to register within the time provided), after the application fails to start. But I believe this is more a result of the problem I'm having and not the cause.

My install is on a Dell XPS laptop, and not inside a virtual machine.

I'm not prepared yet to do a clean install and would like to have it work with my installed apps.

This sounds like a problem with the upgrade from a stable version of an operating system to what basically amounts to a beta. – Ramhound Mar 1 '12 at 13:58
Yes, i'm positive it is related to the upgrade as well, but would still like to fix it without having to do a clean install. – Gabriel Mar 1 '12 at 14:39

Problem seems to be affecting a lot of users, seems either related to the ATI display driver or the upgrade from Windows 7. – Gabriel Mar 2 '12 at 13:28
