I successfully installed Starry Night Celestron 7. When I double click the executable the app starts to load with a splash screen, which says;
"loading Disk Layers..."
"Version: 7.6.3.1377 keEW | <my name> <serial number>"
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.
