I have the same problem. Photoshop 7 supposed to be compatible with windows 7. Cannot reload. When I have loaded I get "Cannot initialize Scratch disk full". Is there a way to eliminate this.This program was working fine until the scratch disk full error. It works on my other computer but something is amiss on this one. When I try to install it takes 15 minutes to start the installer and I get the message to set scratch disk on different volume but then comes the Scratch disk full and closes.
