For several years I have had Photoshop LE 4.0 and Pagemaker on the Dell (2.6gHz, 3 gig RAM Windows XP sp3) working very well. Recently those applications have ignored the call to work. I uninstalled them and attempted to load them again from the same disk they came from in the first place. There is no response to the run command. It has been somewhat like a year since I did serious work with them, in which time there have been one or two updates to the computer (don't ask me what) and since when I have deleted some other applications (again, don't ask).
Has anyone any suggestions? Is it possible that upgrades have destroyed the ability to run PS? Is it possible that shared .dlls deleted by removed applications were necessary to PS? Is it possible I am seriously screwed?
