I am using the latest update of Windows 10, Fall 2017 Creators Update, I think. Anyhow, Windows 10 was not listed for this game, but I love Creatures, so I took a chance that I could get it to work. Creatures 1 seems to work right away, after installed. But Creatures 2 wouldn't get past the World Launcher. It kept giving some obscure error message. Using Google, I finally found someone that had gotten it work on Windows 8, and he wrote that Creatures 2 would not work if run as Administrator or in Compatibility mode, but that you had to request the reduced color mode, and set it to 16 bit. Voila! It works very well. The menus are a bit wonky, but they work. I am happy. Thank you (to GOG).
