Oh, man..... something isn't deleted.
Someone recommended a reg tool that
might find it. Not sure but I think it was recommended by the downbelow website called registry mechanic:
http://www.pctools.com/registry-mechanic/
That might find the remaining clutter and allow you to delete it. Too bad, I had a program that would do that in the ME days but don't have it any more.
I'm not tech support but I'm pretty sure the full version D2D would see the remaining DVD install. I hate giving registry advice. Well, anyway this bumped the thread.

You could make a restore point and follow AVGWarhawk's steps with the reg (at your own risk) ... ouch!
