Photoshop cs5 upgrade
I recently bought cs5 upgrade. I have the web premium cs4 on my computer. I also have the whole program of photoshop cs2, but it is not installed. I read that an upgrade will not install over a collection. I had a hard time with the trial photoshop cs5 and am wondering, do I have to uninstall my web premium, install my photoshop cs2, then install the upgrade? Or will the upgrade ask for the previous version's serial number that I have and then install it? I am concerned because the trial kept not wanting to install, but eventually did. Haven't used it much, so dont know if it has problems.
