A client is uniquely identified by a ComputerID and a ComputerName. A value of -1 means there is no limit. The **enforceMaxTrialsWhenActivating** controls whether QLM limits the number of trial keys per system. Once the number of trials per client has been reached, you have 2 options to allow a specific client to activate: 1. Increase the value of **numberOfTrialLicensesAllowedPerClient** 2. Deactivate some of the activated licenses To deactivate some of the activated licenses: * Launch the QLM Management Console * Go to the Manage Keys tab * Search for all licenses that match the client's Computer ID as shown in the screenshot below * For each found license, you must either delete the license or deactivate it.
