I am using original discs with serial number stickers for CS3 extended and CS4 on a 2008 MBP with 10.8.
While still having CS3 installed, and reinstalling CS4, the correct serial # request of pre upgrade version CS3 was repeatedly rejected.
So I removed everything Adobe from HD, ran Adobe cleaner which found nothing.
Now I am unable to install CS3 as I get "problem with installation, contact Adobe" message...
I manually removed everything Adobe related from HD to no avail.
Who has the know how to solve this conundrum?
Thank you for your help,
Only Adobe Customer Service can help you with serial numbers. Call them on the phone.
We're just users here, though some Adobe staff contribute here as volunteers.
Just a possible idea of what might be going on...
Don't I recall that with 10.8 you now can ONLY run 64 bit code? Apple is pretty ruthless about leaving older versions of things behind without support.
Is it possible Adobe had 32 bit code somewhere in the installers for older versions, designed to work on Macs running OSs that ran both 32 and 64 bit code? Have you seen anyone able to install a version of Photoshop older than CS6 on Mountain Lion?
