When you delete the active license key deployed to a managed device, the application will continue working on the managed device.
To delete a key file or activation code from the Administration Server repository:
Check that Administration Server does not use a key file or activation code that you want to delete. If the Administration Server does, you cannot delete the key. To perform the check:
In the main menu, click the settings icon () next to the Administration Server.
The Administration Server properties window opens.
On the General tab, select the License keys section.
If the required key file or activation code is displayed in the section that opens, click the Remove active license key button, and then confirm the operation. After that, the Administration Server does not use the deleted license key, but the key remains in the Administration Server repository. If the required key file or activation code is not displayed, the Administration Server does not use it.
In the main menu, go to Operations → Licensing → Kaspersky licenses.
Select the required key file or activation code, and then click the Delete button.
The selected key file or activation code is deleted from the repository.
You can add a deleted license key again or add a new license key.
