[Thermo Scientific License Manager]
Context
If you no longer require a local license, such as an expired trial license, you can deactivate it using the Deactivate action.
It is important to note that if you intend to reinstall the deactivated license in the future, it’s recommended to use the Transfer action instead (see article KA-01237 "Offline Local Transfer"). This ensures that you can save the license activation codes for reuse subsequently.
