Description

The traditional perpetual, unlimited licensing model can serve as a basis for other, more creative marketing strategies, for example:

>Your software is initially supplied with a perpetual license. The end user purchases additional modules as required.

>The initial release is supplied with a perpetual license. You plan to implement more sophisticated licensing models with future releases.

>A limited license (“bronze”) is converted to a perpetual license (“gold”) for additional payment.

Implementation

1.Select the executable file that you want to license, and determine by which Feature ID it will be identified.

2.Select your protection method:

Envelope-based automatic implementation
Protect the executable file using Sentinel LDK Envelope, specifying its Feature ID.

API-based automatic implementation
In your code, insert a Sentinel Licensing API Login call to the Feature ID.

3.In Sentinel LDK-EMS, create a Product that includes the Feature ID and define a perpetual license for the Feature.

4. Use the RUS utility to update a license currently held by the end user with the new license.
