I have an imac G4 running OSX 10.4.11 and am using Quark Passport 7.3, Illustrator CS2 v 12.0.1 and Photoshop CS2 v 9.02 - all work well. In the past I have copied this software over to other similar imacs and all worked well but now I am having this problem... I just purchased an imac Intel Core 2 Duo running same OSX 10.4.11 and none of my 3 main programs will open. Quark copies to it but when I click to open the appl it blinks but does nothing Illustrator locks up with spinning wheel, and Photoshop says user id and/or serial no is invalid and must exit now. Ugh, Ugh, can anyone help me to find the versions of these 3 programs that are compatible with the Intel imac?
