ArcGIS Desktop and ArcInfo Workstation provide two different installation options:
1. Install ArcGIS for Individual Use
2. Install ArcGIS on a Network
The Individual Use option installs ArcGIS on the machine intended for use. The term Individual Use is not indicative of the software licensing, but instead indicates that the software will be installed for use on one computer.
The Network option installs ArcGIS on a network server so users can install it on their individual machines from a central location. This option does not provide a working copy of the software.
Please see the Install Guide on the ArcGIS CD for more information.
