Got it.

I was selecting the wrong menu item from within PPT menu. For those in a similar situation:

Select the funky round MS symbol ball.
PowerPoint Options (down on the bottom)
Add-Ins
Manage Disabled Items (bottom of the drop down).

For some reason I wasn't seeing that earlier and the manage COM add-ins option
returned the error message per my original post.

D'Oh.
