I am trying to do the newest library update for AC15 (as well as installing the accessories for AC15) on an apple powerbook running 10.8.2. The installers download fine from the internet and work on our other computers which run an older system. When I try to run them on 10.8.2 it says the installer is broken.
Has anyone seen this?
I really need to get the accessories because the project I migrated from AC13 to AC15 uses them and now I can not edit them.
