Hi and thanks for your question.
This may not be the answer you wish to hear, so please don't shoot the messenger. According to Adobe, Acrobat 8 Pro will not run under any version of OS X newer than Mountain Lion. Acrobat 8 has reached end of life and no further updates or fixes will be released, as well.mIn order to run Acrobat under the newest releases of OS X, you would need to upgrade to a newer version. :-(
You are very welcome. I'm sorry I didn't have a more positive answer for you!
