I haven't found a way around this. Ended up giving up - the other updates work, but the transition catalog, and the latest Reader 11 catalog don't. I don't understand why the latest Reader 11 catalog isn't in SCUP available catalogs like the old one still is and the Flash one... Why don't they update that? You have to manually download - and then run into this unanswered issue instead...
The admin enterprise deployment guide is a joke too BTW Adobe. I think my students could write a more detailed guide.
