The registry version might be the politically correct way to do this, but you might find it easier to just try instantiating the control and trapping the error if it fails. This is also the most failsafe way... the correct registry keys might exist, but something else could have changed: the file could have been moved, a dependent file could have been moved or deleted, whatever.

IOW, the only surefire way to see if your control will create is to create it.
