If you purchased a 5-user floating license, you will get a license key that allows 5 user connections. You need to place this key file into a location on the server computer (that will have the license server program running) and then start the license server. After that, clients can start VP-UML and select the license server host as the license key repository, then start to use VP-UML. It does not matter where the client’s computer is, it can connect to the license server as long as the number of active connections do not exceed the purchased user amount.
