Invalid Class String (Database diagram)

[Cowboy (Gregory A. Beamer)]

I am getting an error trying to create a new database diagram. I assume that
some underlying COM component is not registered properly, but I am not sure
which one, as there is no Event Log entry, only the error in SQL Management
Studio.

===================================

Invalid class string
(MS Visual Database Tools)

Solved by uninstalling and reinstalling the tools.
