Ok, so. I have a copy of Photoshop 5, a physical copy, in the original box. I tried to install it on my computer, and actually did so successfully--it recognized the serial number from the box as correct and did a full install. However, when I actually opened Photoshop for the first time, a message came up saying that the serial number was invalid, and my options were to enter a new one or wait until next time, when I'd have to enter a new one for Photoshop to run.
I haven't closed it yet because I need it for work and don't want to risk it not running. Why would my definitely valid serial number not work? I double and triple checked what I typed in, and it initially accepted it, only rejecting it after installation.
I'm on Windows 7.
Welcome to the forum.
Did you purchase this copy of Ps 5 (Assume CS5, but please correct me, if it is the very old Ps version 5) from Adobe, or a 3rd party?
If from Adobe, log into Adobe.com with your Adobe ID and go to My Products. Verify the S/N there.
If from a 3rd party, it could well be that the S/N provided has been "used up."
Yes, you're correct, CS5.
I purchased it from a third party, and originally installed it on my personal computer at the time This is the first time I've tried transferring it to a different computer.
By "used up," does that meant there's a limited number of installs for each serial number? Is there anything I can do?
