For me i had to Uninstall WSUS but tell it to leave the DB. Reboot. Then find the Reg Keys as explained in one of the links. I had to delete these rather than change. After this uninstalled Windows Internal DB from Add/ Remove. The reboot. The manually delete the stuff in c:\windows\sysmsi\SQL Server 2005. Then check the :\WSUS or wherver it was installed was empty.

Then i was able to re-install from Package.
