CS2 in Windows 8

Had Photoshop CS2 loaded on computer running Windows 7 - no problem. Just loaded it onto new computer running Windows 8. Loaded OK according to on-screen messages but when I run the programme I tries to fill in Registration and got the message "Could not complete your request because of a program error". Then tried to crop a photo and got the message "A required application library failed to load and the product cannot continue. Please reinstall the application", Have done this twice but still the same problem and same messages. Tried updating but no updates available. Any clues as to the problem and perhaps a remedy??
