Are you talking PS3 which is probably 16 years old or CS3 probalby 8 years old?
Did you load files from disk? Copying files from one computer to another will not work.
I am talking about CS3,
I spent an hour and a half on chat with adobe but still the same problem.
I removed the adobe files from ~/library and /Library
I also did something in terminal
and still it says "licensening has stoped working.
I have CS 8 on the desktop with a single license and wanted CS3 on the laptop just to have a photo program on it.
I also have the original disks and loaded from them
