The Legacy Licenses tab contains application license information for older Laserfiche products.
The Laserfiche Windows client 8.2 and later does not require a license to install, and so there are only specific application nodes for the Laserfiche Windows client 8.0 and 8.1. Snapshot license information is part of the Laserfiche Server license. Snapshot can be installed without a license, but can only store documents in a repository hosted on a Laserfiche Server with the Snapshot license add-on.
The Laserfiche 8.0 and 8.1 Windows client and Snapshot do require licenses to install, but the same license can be reused for these applications, and so it is not necessary to register application instances for these applications.
