Custom view can run on any Windows 2000 (sp1 or greater) or XP (sp 1 or greater); workstation or server. Ideally, custom view is designed to be on a supervisor's desktop so they can access realtime information during the day. Although you can run custom view on a server, I would not recommend since custom view is a named license. Unless only 1 person is accessing it on a server, it would not really be ideal to have on a server. I run it on XP (sp2) P4 3.2gHz 1gB RAM desktop. I am running version 4.0. Just remember to install the schema before the custom view director/producer. Have fun...
