.NET for AmiBroker has 3 licencing models to cover the various needs of a single user to large companies.
Single user license
Single license is recommended to individuals and small companies. The single user license is similar to AmiBroker's licensing model. It is valid for two computers. E.g: your desktop and your laptop.
Version upgrades (e.g: from v5.80 to v5.90) are free from the date of purchase for new releases of the next two years .
After the two years free upgrade period the version upgrade is at 50% discounted price.
Upgrading to Developer Edition
You may choose to upgrade from Standard to Developer edition anytime. In such case you pay only the price difference of the licenses of the software editions.
Single user licenses are tied to machines by license keys.
(Software license keys are tied to the machines via hardware finger prints. No USB key or any other type of hardware device is used.)
Service providers should choose subscriber licensing to provide services to their vast customer base. As subscriber membership changes continuously over time this licencing model is NOT computer bound, it needs NO local licence key deployment.
In this licensing model service providers validate their subscribers at logon and allow them to use their services via a licenced .NET plugin. Client machine can be replaced easily as setup of a client machine does NOT require any additional step to install local licence key.
Companies having great number of employees using AmiBroker & .NET for AmiBroker on local computer network should choose volume/network licensing.
In this licensing model machines have no locally installed licence keys. Machines aquire "floating" licence key from a network server while utilizing plugins.
