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 com
puter 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 occa
sionally 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.
