Get the serial number for photoshop just in premium creative suite to reinstall photoshop 3 You don't need a serial number for a trial. I reinstall my photoshop 3 on my new mac, but need the individual serial numbers of my old creative suite for photoshop until I can reinstall or upgrade.
I still have got to Adobe before each upgrade. You should get it from your records, you can't count on Adobe to remember forever. If the chances of CS3 running in the latest Mac OS are very small. If you upgrade the Mac you need a budget for upgrading applications. You want to update of Lightroom 5 in Lightrom 5.7.1.
