License Manager Basics

A concurrent use license allows copies of ArcGIS Desktop, ArcGIS Engine Runtime, and ArcInfo Workstation to be installed on numerous machines. The ArcGIS License Manager, once installed on the network, keeps track of the number of copies of the software that can be run simultaneously. The same ArcGIS License Manager can be used for all ArcGIS 9.x concurrent use software products. The number of concurrent use seats in your license file determines the number of copies of each software product that can be run simultaneously.

You only need one ArcGIS license server per network to manage all your concurrent use ArcGIS 10 and 9.x software products. The license server can be a Windows, UNIX, or Linux server and will manage Windows, UNIX, and Linux ArcGIS software products. For example, a Windows installation of ArcGIS Desktop 10 can obtain a license from a Windows, UNIX, or Linux License Manager.

Once your ArcGIS License Manager is running, any computer on the network can access that License Manager to run the software applications.

Authorizing licenses on your license server

After purchasing ESRI Concurrent Use software products, you will receive an e-mail from ESRI Customer Service containing the authorization information for your purchased products. You will need this information to authorize licenses on your license server. You first need to run the license manager installer and use the ArcGIS License Server Administrator to authorize licenses before starting the license service.

Detailed installation instructions can be found in License Manager Installation and Startup.
