Here are the instructions we received with our licensing. It is not clear what we do with the activation key, we typically use these for installation or re-activation of a specific product. This is a Rio system though.
The updated Laserfiche product licenses are available now on the Support Site. To obtain the updated licenses, log on to https://support.laserfiche.com and click “My License Files” or “My Clients’ License Files.” If the product is licensed by activation, click "My Activation Keys" or "My Clients’ Activation Keys" to obtain the keys.
