Licensing Concepts

In the descriptions of the Master Key licenses model, the following concepts are used:

>Unlocked Trialware Product: A Product that can be used as trialware, or during a grace period. Unlocked Trialware Products are not locked to a specific machine and do not require activation for a limited period. Unlocked Trialware Products typically have a duration of 30 to 90 days or 30 executions. This period can be set to begin either from the date of first use of the application or from the date that the license was generated. (The Unlocked Trialware Product was formerly referred to as a Provisional Product.)

>Unlocked Unlimited Product: A Product that does not lock a protected application to a specific machine and does not necessarily impose any licensing restrictions on the use of the protected application. (The Product can be granted a perpetual license or can be limited to any length of time that you choose.) With this license type, the vendor can use Sentinel LDK to protect the application, but can use a different mechanism to license the application (or can impose no license restrictions on the application).

>Activation: The process in which an SL key is locked to a specific computer. Following Activation, the protected software can be used on the end user's computer according to the license that was installed during the Activation process.

>Concurrency: A licensing attribute that can be specified to allow a single protection key on a computer in a network to be used by one or more instances of a protected application running on different computers in the network.

Concurrency is defined separately for each Feature in a Product.

Each instance of the protected application that can be used simultaneously is referred to as a network seat (or a floating license).

Network seats are not assigned to specific users. Instead, the concurrency attributes specify how many instances (network seats) of the Feature in protected application can be used simultaneously within the customer’s network. The customer purchases a specific number (or an unlimited number) of network seats.

For example: A customer purchases 10 network seats for the Basic Feature and 5 network seats for the Advanced Tools Feature for a protected application. As a result, 10 end users can run the application and use the Basic Feature simultaneously. 5 of these users can also use the Advanced Tools Feature simultaneously. All the users must be part of the network where the protection key is located.

Management of the license in the network is controlled using the Sentinel License Manager.
