EViews

The EViews License Management System regulates both EViews concurrent use (floating), and laboratory licenses across a set of machines connected by a network. With this system, licenses purchased from IHS Global Inc. are installed on a central computer running the EViews License Server. The license server’s job is to communicate with concurrent use clients and laboratory machines, granting or renewing licenses to run EViews.

Under concurrent use licensing, whenever a copy of EViews is launched on a client machine, it connects to the license server and requests a license. If licenses are available, the license server grants the request and the copy of EViews is allowed to run. If all licenses are in use, the license server denies the request and the client machine is unable to run EViews at that time. Under laboratory licensing, copies of EViews launched on laboratory machines must occasionally connect to the license server to renew their licenses. There is no limitation on the number of licenses that may be issued, but each license must be renewed within 30 days, otherwise the laboratory machine will not be unable to run EViews until the license is renewed.
