By golly, I finally got PS7 to list in the "Open with"FILE. I just had to string the existing apps to where it said : "more apps" so I searched the C drive where the program was located, clicked on the PS7 icon & viola, it placed the app in the "open with" file. Of course that worked on my PC, not sure if it will do the same on the wife's pc. Her win10 seems operate differently than mine. She has a store bought all-in-one which came with it. Mine was a free install on an old tower. A real teaser for sure..................
