In most cases, the license key is not provided with the application. Software installation is followed by a registration process, and the license key is then despatched to the user by email. Trial keys can be used to gain immediate access to the software.
The license system described here was introduced at Release 7.2 of GenStat (7th Edition SP1), and version 2.0 of ASReml and SAMM. The notes are not relevant to earlier versions of these programs, except where specifically indicated (e.g. when discussing upgrades).
FLEXlm and FLEXnet are registered trademarks of Macrovision Corporation. As of version 10.0, FLEXlm was renamed FLEXnet (i.e. FLEXnet v10.0 followed after FLEXlm v9.5). Both names are used in VSN documentation and can be regarded as equivalent.
Note that in some cases multiple or site-wide licenses may be provided in this form, according to specific circumstances.
This form of licensing is particularly suited for "counted" licenses, where licenses are issued from a limited pool. Any user on the network can have access, until the pool is exhausted. Site-wide licenses may also be provided in this form. Licenses for different software products can be combined so that they are maintained within the one system.
When a network license is provided, the application software can be mounted on a network drive or on individual machines, or a mixture of both. An auxiliary license file installed with the application directs license requests to the FLEXlm license manager running on the server.
The trial key can also be used to gain access to the software whilst awaiting delivery of an Individual License, but note that they cannot be used for a network installation.
Note that trial keys are not necessarily available for every software product on every platform. Where the facility is provided it will be offered as an option following installation.
