Module Licensing
You must license the most important modules of Exchange Services. Licensing these modules ensures that the programs run only on the hardware for which a license has been purchased. The license key for your computer is computed based upon a unique identification number. This number, referred to as the serial number, is displayed during the installation.
Additionally, Module Licensing shows a list of all available modules in Exchange Services. It shows the licenses that are installed for each module and the number of licensed channels on this site. To create a license, provide your serial number. You will then receive a license file named license.d. This file must be stored in a subfolder of the server installation directory. By default, this folder is C:\Rocket\Eurexc\server.
