MM2 Help w Install and Save

Can't get MM2 to install. Same three dll failures as everyone else here. If I try to register them from the command line I get DllRegisterServer in C:\Program Files\Movie Maker\whatever dll I tried failed. Return code was: 0x8007007e. A search for this yeilded nothing. When in MM after I add a clip the app crashes EVERYTIME. Couldn't find anything on Papa John's site to help. Any help would be appreciated.
