Time-limited Versus Perpetual Licenses
Licenses can be time-limited or perpetual. Time-limited licenses are valid until a given date, which is shown in the product splash screen when you start the software, or in the About dialog (accessible from the Help › About menu). After this date, Thermo Scientific software will stop working. This is usually the case for trial licenses, Beta licenses, or renewable rented licenses (i.e., yearly subscriptions).
