I am running Leopard and have downloaded the trial version of Photoshop CS3 but I cannot install due to the conflict message. I have Adobe CS installed but wouldn't have thought that would have conflicted with CS3. I have cleaned my system library prefs of any CS3 files but still cannot install. Short of removing all Adobe CS apps ( I am backed up so I could if necessary) I cannot figure a way to achieve installation. I have checked the Adobe website for any help but had difficulty finding any way through the maze!! Any help please?
