In order to be able to use the EPESI Store you first need to register your installation and obtain a License Key. All your purchases will be bound to this installation and License Key and at any time there can be only one installation running with the specific License Key.
Some premium modules are available for free, but in order to use them you still need to obtain a license for them through the Store.
Once you obtain the license you are eligible for all the future updates of the module without any additional payments. Also, any changes in prices will not affect any of the modules you already have license for.
Note: in the current AdminLTE UI, the license key display previously reachable from the top panel wasn't found during an August 2026 review of the live interface (checked the header, Launchpad, and My Company/My Contact) — it may have moved, been folded into Administrator → Modules Administration & Store → Invoices, or be presented differently now. Flagged for the Epesi team to confirm the current path rather than guessed here.
