At v10, it was nice that you could roll back individual Service Packs.
Ive just rolled forward to 10.1 SP1 on my dev machine (not a fresh install), but it would appear this option is not available at 10.1.
Anyone know of a way to roll back the Service Pack without having to do a re-install?
EDIT - As an Esri distributor employee I have an pre-release of SP1, and I assumed it was the same final version that would be made available to clients.
I would like to suggest leaving this Q open until the final release is made available, and I will re-test and either edit my Q accordingly, or vote to close the Q off if its not an issue anymore. Apologies if I have caused any confusion. I can say that there is some nice new stuff to play with in this SP :)
