Concurrent-use licenses are controlled by a license manager operating on an organization's network and can be checked out by any computer on the network. One license manager can administer the different ESRI software. ArcEditor and ArcInfo are only available as concurrent-use licenses. ESRI licenses ArcGIS extensions as either single use or concurrent use. ESRI provides an administrative utility for controlling which software is operational on that machine and listing additional concurrent-use licenses available on the network.
Users can switch between software licenses depending on their role or daily tasks.
