I've installed my CS3 on my new comp it's saying my PS trial has expired. How do I get it to acknowledge CS3?

I needed to start editing some photos fairly quickly on my new computer. And my CS3 disk was buried in a closet so I downloaded the trial version of photoshop cs3. I assumed when I installed my creative suites it would acknowledge the fact that I had a disk and would by pass the trial. It has not, now I can use every program on my Creative Suites disk EXCEPT for photoshop which is saying my trial has expired. How can get it to acknowledge that I do not need to purchase photoshop?

You need to activate CS3. See if there is a CS3  menu item Help>Activate

I'm able to open all my other programs on CS3 without any issues. It's just photoshop that will not run without entering in a photoshop specific serial number.

Find your serial number
