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.
