I upgraded to Windows 8 (mistake) then further to Windows 8.1 (bigger mistake) moved in Photoshop, and other programs in, when a few days later the whole system crashed. Nothing I did would open it up. In total frustration I set the whole thing aside. Since it is impossible to get a copy of Windows 7 Pro I rebuilt the computer and reinstalled Windows 8, NO Upgrade beyond, and want to install Photoshop. But you may have it on record, that it exists on a now non-existant computer.
