Just installed Starry Night Orion SE. When I double click the executable the app starts to load with a splash screen, which says;
"loading Disk Layers..."
Version 8.1.0.2059 keEW
Then a popup with the message "The planet data file could not be found. Try reinstalling from original disks." and an option to Quit only.
Presently running Win 10 Pro.
Version 2004
