I've been running MC12 since the beta with no troubles. Today I decided to download the latest update, and upon attempting to install it, got the following message:
Windows Media Format Setup failed. Error Code 0xc00d2b00
Installation is blocked because your computer does not meet one or more of the setup requirements. Please visit Windows Update to download the appropriate updates from Microsoft before installing WMF.
That error code comes up with zero results on this site and on microsoft.com, so I don't know what updates I need to install.
MC12 won't start at all now. Any time I try to start MC12, I get the error message, "Media Center has encountered a problem and needs to close. We are sorry for the inconvenience." I get the same message if I try to uninstall MC12. Rebooting has no effect.
I'm running a legal copy of Windows XP MCE. Any suggestions?
