For All users:
The higher the speed processor and the more memory, the better your experience will be! The first time you install Space Update, a high-speed internet is essential to download the sky movies, if you wish a different latitude or year from the one on the disk. Both Earth Update and Space Update use the internet to bring down the latest images... but are still extremely valuable without one!

SPACE UPDATE
You need 450 MB of free hard disk space for all of SPACE UPDATE, or 50-140 MB free if you only wish to show one of the modules (Sky Tonight is the largest because of the skyview movies included). Monitor requirements are 800x600 pixels, with millions of colors. No keyboard is necessary - only a mouse, trackball or trackpad and clicker.

EARTH UPDATE
You need 450 MB of free hard disk space for all of EARTH UPDATE, or 50-120 MB free if you only wish to install one of the spheres. Monitor requirements are 800x600 pixels, with millions of colors. No keyboard is necessary for the display - only a mouse, trackball or trackpad and clicker.
