A floating license can be used with unlimited installations of Geneious. The number of Geneious installations that can run unrestricted is limited by the number of "seats" specified for the license. For example, a five seat floating license will allow 5 simultaneous users to run Geneious unrestricted.
Floating licenses usually require the installation and use of the Geneious Floating License Manager (FLM) on a single computer located on the same local network as your Geneious installations.
A floating license can be used to activate a single installation of the FLM.
The FLM is a FLEXnet license server. A link to the installer for this software will be sent to you at the time you receive your license.
The FLM software needs to be installed on a computer on your local network with a fixed IP address/host name that is always turned on (with sleep or power saving features disabled), with the appropriate firewall ports (by default 27001 and 49630) opened to enable the Geneious client machines to access it.
All Geneious clients activate by going Geneious menu Help -> Activate license, and using the option Use Floating license server. Set the appropriate Server host name or fixed IP address to allow Geneious to contact the FLM to activate.
If you purchase a floating license is sent to you as a text file, and you do not receive a link to the floating license manager software, then you have been issued a peer to peer license that is activated directly in Geneious using the option Use license key.
