I'm attempting to install a very old version of Photoshop, CS3 onto my computer. The version apparently is so old that the activation servers are no longer used, so once I put my serial number in it only allows me to have a 30 day trial of the program I own.
I contacted Adobe support and they gave me a link to a page that instructs me to delete the program, then I use Creative Cloud Cleaner, and finally I navigate and delete a cache file. The instructions then instruct me to reinstall CS3 from the CS3 product download page, however the program is no longer listed.
I went through this process and attempted to reinstall via my CD, and once again I'm back where I started... with not being able to activate the program.
I can only guess that support agents read from a computer screen of information, and that the information has not been updated... I contacted the Adobe employee who monitors these forums, so hopefully this won't happen to someone else
