Let's set expectations accordingly. Neither the application nor the OS is supported by either application vendor or OS vendor. That being said... What do you mean "exactly" by the term "transfer" in your statement? If you are talking about simply copying it from one machine to the other machine, then that process won't work. You need to install the product on the new system. Also Acrobat version 8.x was initially released in 2006 which was 10 years ago. The version of Mac OS X for release was 10.4.x Tiger and the version that you are attempting to install on is Mac OS X 10.7.x Lion which was release in 2011. The Mac OS X operating system changed drastically between those two versions. Also Acrobat 8.x would no longer have been tested nor supported at that point.
Thanks, Steve.
I seem, at the very very least, to have found a fix for this week's work. A step-by-step guide to help people getting just the error message I posted, here at:

The second solution worked for me, as I was finally able (using the 8, installed by disc) to get a screen up to ask for my serial number. I put that in & voila!
Your thoughts make me nervous about this fix lasting but I'll take what I can for now.
Best,
Stacey
