According to the information that I could dig up online, the application has been last updated in 2001 and is compatible with Windows 95, 98, ME, 2000, NT. Since it doesn't even work on Windows XP, I believe that the only way you could use the program on a modern operating system would be to install it through a DOS emulator like DOSBox.
