I'm using Illustrator CS2 for Mac, v10.4.
I believe the problem may be with the fonts that need to be activated for Illustrator to open, b/c it quits as the program is starting up as it's cycling thru the fonts in the activation window. It stalls for a few seconds and quits after Apple Gothic comes up, but I don't think that font is a problem. It may be another font that I may have inadvertently deactivated in my font utility recently (but can't remember which would cause this).
I've reinstalled Illustrator, repaired permissions, and removed the .plist preference, but it still won't start.
Help would be greatly appreciated!
Try cleaning out your font caches and checking for corrupt fonts. You also mention nothing as to what font manager you are using.
Fixed it myself after noticing a similar message thread on the forum.
I deleted the Adobe Illustrator CS2 Settings folder and the com.illustrator.plist from the User/Library/Preferences folder. Put them on the desktop first then restarted Illustrator. Worked fine. Then trashed the old settings and .plist file---Illustrator will generate new ones at startup.
