There is a documented problem with the CS4 installer hanging at 90% when installing on a Mac. I have a new iMac and have this problem.
Adobe's on-site solution is to create a new User with admin privileges, but this did NOT work for me.
I tried installing from the original CD and from a downloaded version of the software with the same bad results.
Can someone help me resolve this issue?
I'm not running the whole CS4 suite on my Mac under Mountain Lion but I am using Dreamweaver CS4 with no problems.
Have you got Adobe Air installed? If so uninstal it and also run the uninstaller for CS4 and then try again.
I uninstalled every Adobe product I had, including Adobe Air, and removed all Adobe items from Preferences, System, etc. After creating a new User with admin privileges I rebooted in Safe mode and still have the same problem. I have worked through all ten of the solutions Adobe mentions on its Web site--all with no success.
This is all terribly frustrating. I don't really have $500 to upgrade to CS6 and need this software badly for image processing and Web management.
