Have you tried reinstalling Acrobat Professional 6.0.2?
No.
Have you tried repairing permissions?
I run DisUtility and DiskWarrior regularly, they repair permissions.
Have you tried to use Preview to read documents that Acrobat Professional
won't read?
Acrobat Professional reads everything, Preview works good too. What doesn't work is using Safari for PDFs, or, specifically, the "bigger" button doesn't work so the pages are usually too small to read. I have Preview set as the default application for PDFs. Is there some way to tell Safari not to open PDFs but instead use the default application? I don't see anything in the Safari Preferences to do that.
When you are running the 6.0.3 updater are you just selecting the Acrobat
Professional Folder or the actual Application itself.
I selected the Acrobat 6.02 Professional application.
I see what the problem is. On the Adobe website when you click to download the Acrobat Professional 6.03 updater it instead downloads the Acrobat Reader 6.03 updater. I'll e-mail Adobe about that. Without the 6.03 update I can't update to 6.04.
I still don't see what the problem is installing the 7.07 Reader. I've tried half a dozen times.
