If you no longer require a local license, such as an expired trial license, you can deactivate it using the Deactivate action.
It’s important to note that if you intend to reinstall the deactivated license in the future, it’s recommended to use the Transfer action instead. This ensures that you can save the license activation codes for reuse at a later time.
- Launch Scientific License Manager.
- In the Licenses screen, select Deactivate either for a multiple list of product licenses.
or for the license you want to deactivate, click the 
icon.
- In the Deactivation mode display, click Offline deactivation.
- In the Deactivate License(s) display, confirm the deactivation by clicking the Continue button.
Follow these steps for offline deactivation:
1. Click Create request file in the Offline license Deactivation (1/3) screen.
