Recognize a license number by product
Details for licensing your Genero products are delivered by email. By examining the license number, you can identify the product it licenses.
Four Js provides a license number and license key with the product package. For a perpetual license, you will get a maintenance key with your maintenance contract. For a subscription license, you will get a subscription key.
Before you begin Genero product licensing, locate your email message that contains the
following:

A license string is an encoding of your license number, license key, maintenance/subscription key, and customer code. It is easier to use in license installation and upgrading.
