I'm trying to de-activate my Photoshop CS3 Extended so I can uninstall it and reinstall it from my old XP computer to my new computer which is Windows 7 . There's supposed to be a tab for De-activate under the help menu but there isn't when I click on help. I have the box, Disc and license so reinstalling it should be easy if I can just get it de-activated. Thanks for any help.
Contact support to reset activations then simply install the program on your new machine.
