Installing and activating Photoshop CS4 Extended
I have Photoshop CS4 Extended disc, student license, serial number. Have already used disc to install on several Macs, some no longer functional. I am planning to buy a refurbished MacBook Pro from OWC Eclipse with El Capitan OS, exclusively for using CS4 Extended. Have no way of knowing if CS4 was ever installed on the machine. Will be requesting several upgrades on new MBP so don't know if 90-day warranty will be honored if CS4 installation/activation fails. How likely is it that I can install and activate CS4 on my proposed purchase?
I see some CS4 for sale on ebay, with serial number, etc. One "new, sealed" for $400. Are these more apt to work than disc I have? It may be apparent that I don't know much about this stuff. Thanks.
