This version of 3DAstronomer works on all Microsoft operating systems including
1998 2000 ME XP Vista Windows 7
3DAstronomer will work on almost any modern computer, however the faster it is the better. You will need to have Open GL drivers running on your graphics card. Most cards simply require you to update to the latest release to install this.
Please note that the download files are reasonably large. The game itself is over 400megs. Due to this reason physical versions of the scenery sets are available in the members area.
If the physical game is purchased you will need a working DVD-Rom drive attached to your computer.
