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.
Found the solution in another thread here: uninstall Acrobat Pro and reinstall it. Then apply the updates/patches.
Worked for me.
