During the Laserfiche Server installation, you will be asked to provide an activation key for online activation, to provide a license file, or to activate to your Laserfiche Rio license manager. Your license information will determine what edition of the Laserfiche Server you will install, your user licensing, and what features are included with the Laserfiche Server. You should locate your activation key or license file, or ask your Laserfiche Rio administrator what license server to register to, before beginning installation.
See Installing the Laserfiche Server for complete instructions on licensing and activating the Laserfiche Server during installation.
