Did you reboot your computer after you uninstalled Windows
Messenger 5.1? If you didn't, that may account for the messages
you received about a newer version still being installed when
you went to install version 4.7. Deleting the registry keys you
found may have caused the problems you're dealing with now.

One thing you might want to try is reinstalling Windows
Messenger version 5.1. It's available here:

http://www.microsoft.com/downloads/d...displaylang=en

You'll be asked to restart your computer when the installation
finishes. Once your system restarts, check Remote Assistance
and see if Windows Messenger shows up as a viable option.

I did find an old post on this subject that you might want to
take a look at.
