Alright, I finally fixed the issue, as before I was unable to finally the registry value to delete as I was looking under the wrong HKEY_... folder in regedit. I also ran into the issue of not being able to delete the registry as access was denied.
The solution for we was the delete the registy HKEY_LOCAL_MACHINE/SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\Photoshop.exe and if unable to delete registry due to "access is denied", then you have to change the owner of the registry by right-click on registry-->Permissions-->Advanced-->Owner (Change), Advanced, Find Now, Select Name: Users (at bottom of list), OK, OK, OK, then check the "Full Control" box to give you access to delete the registry. Apply. Then right click on the registry and click delete. Then install the program and all is good.
Great, we really appreciate your efforts.
