Objectives
While this license manager is a full feature library, we are only going to be using it for obtaining trial licenses.
We want to use this library because it does a good job locking down a machine that once we have issued a trial. Customers can uninstall/reistall the application, but they will not be able to get another trial license on that machine unless we reset the license from the cloud.
Use Case #1: New Clean Installation - Obtain a tria license for a new clean installation of the application.
Users will be able to download the application and install it on their machine. When they run the application for the first time, they will be prompted to enter a license key. The license key will be validated against the LicenseSpring server and if the key is valid, a trial license will be issued to the user. The user will be able to use the application for the trial period. Once the trial period has expired, the user will be prompted to purchase a license to continue using the application.
Use Case #2: Key Deactivation - Deactivate a license on a machine so that the user can move the applicaiton to a different machine.
If the user has a license on a machine and wants to move it to a different machine, they can deactivate the license on the current machine and then, using the same key obtain a new trial license on the new machine. THIS IS NOT NEEDED. Deactivation is not supported since this case the user will simply obtain a new trial license on the new machine.
Use Case #3: Tipwinns Aided License Reset for an Expired Trial - Reset a license on a machine so that the user can obtain a new trial license on the same machine or extend their current license period.
The license manager will lock down a given machine on activation of a trial license. If the trial period has expired, the user will not be able to obtain a new trial license on the same machine. The user will have to contact Tipwinns support to request an extension for the license on the machine. Once the license is reset, the user can obtain a new trial license or the license should extend the trial license already on the same machine.
