When opening adobe photoshop cs2 get error DLL Attempt to load program with incorrect format. Program works mostly but cannot use clone stamp. On attempt to do so get above message and then Required application library failed to load. prod. cannot continue. please install application. CS2 then shuts down. I tried removing preference file but that changes nothing. I also uninstalled and reinstalled Photoshop cs2. Program has worked previously. Windows xp sp3.
