For workstations, VSys One requires Windows XP, Windows Vista or Windows 7/8/8.1. Each machine must have at least 512MB (1.5GB for Windows Vista or Windows 7/8) of memory, a display configured for 1024x768 or higher, and should have a 1GHz or faster CPU. These are the minimum requirements; we recommend 2GB of memory, a higher speed CPU will make your experience faster, and a better display lets you show more information on the screen at once, which is especially useful on some of VSys One's more complex screens.
