I downloaded the catalogs from the above SCCM - SCUP Enterprise Admin Guide, and did a Manual Import of the catalog on the Acrobat 10 updates and still received the message:
18 updates were processed.
0 updates were imported.
18 updates were skipped due to not being updated.
What is really odd is that the updates for Acrobat 11 did come through earlier today, and I received the Flash updates yesterday.
