I've tried several times to install the latest update for Adobe Acrobat (to 9.5.4) and it starts out just fine. Then it stays on the following screen for days at a time:
The option to quit the application is greyed out; I have to restart the computer to close the updater, but the update refuses to progress beyond that point.
Mac software updates are current, as are all other adobe updates. I've updated successfully in the past. I'm running Mac OSX version 10.6.8 on a Macbook.
