Photo Deluxe was an application from 2000. Win 95/98/NT.
It is almost certainly a 16 bit application, and will not run natively in a modern OS. https://forums.adobe.com/thread/1137177
You might get away with Compatibility mode, but I wouldn't count on it.
I understand the love for that particular application, but in the intervening 15 years, there have been many, many new applications to do the same and better, a lot of them free.
