I’ve been struggling with the strangest bug for over a month, every time I launch Adobe Acrobat, it immediately quits. I finally checked the Adobe customer forums and found the most obscure solution I’ve heard in a long time. During a recent MacOS X upgrade, Apple supplied new language .plists and the Acrobat language preferences got scrambled. The solution is to go to MacOS X’s System Preferences:International and modify the Languages list. You can make any change, exchange the order of the bottom two languages, hit Edit and remove unused langauges, etc. and new correct prefs will be written. Now Acrobat will launch again. Oh boy am I happy to have Acrobat running again.
