I need to activate the license key on a new domain but I have exceeded the limit This means that the license key has reached the maximum limit of active domains at the same time, so you must first deactivate the license key from the old domain before activating it on the new one. If you have received the message 'Licensed user limit has been reached' this is normally shown when the number of clients or desktop PC's that have used Schedule it is more than the number of licenses that have been purchased.

In the license server, there's a keep box next to each printer.
