I'm on Mac OSX 10.4.11 and this update fails.
See attached message.
Says I can "re-enable disabled components prior to installing the patch."
(It also says I can reinstall; I strongly prefer not to choose this option.)
It sends me to the "Adobe Support website" for more info;
haven't found anything for this scenario.
Having the exact same problem -- but on OS X 10.6.8, trying to upgrade from Acrobat Pro 9.0.0 to 9.2.0.
The Knowledge Base article I found offers two solutions. I tried both but both didn't work.
Repaired permission, too. Didn't help either.
Still looking for an answer.
