Metro apps won't start under Windows 8 CP

Metro apps won't start under Windows 8 CP

Symptom:

You upgraded from Windows 7 Pro to Windows 8 Consumer Preview, but found the Metro apps won't start when clicked. Sometimes, the app appears to start, the screen fills up with a green background with the app logo centered, but nothing happens afterwards.

You might find the following events when starting Metro Apps:

EventId 10010

Description "The server Microsoft.WindowsLive.Calendar.wwa did not register with DCOM within the required timeout."

 

Resolution:

A few things worth trying:

1. Update video card driver and firmware (verify it by switching to the Microsoft Basic Video Driver.)

2. Fix the OLE registry key. Please make sure to backup the registry before changes are made. (http://support.microsoft.com/kb/322756)

Save the below to a .reg file and merge.

Alternately you can also delete the OLE key and reboot.

Path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Ole

3. You need at least 1024X768 resolution for Metro apps to work.

4. Metro appsaren’t supported if you are running with a built-in administrator account (happens mostly when upgrading).

5. Check if UAC(User Account Control) is enabled.

Path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Ole
