The license key is a sequence of bits that can be used to activate the application for further usage in accordance with the terms of the End User License Agreement. License key is generated by Kaspersky experts.
To activate the application, you need the main license key. If the main license which you are using for the application does not include the additional functionality that you need (for example, Kaspersky Endpoint Detection and Response Optimum functionality), you also need a license key to activate the additional functionality.
You can add a license key to the protected device using one of the following methods: by applying a key file or by entering an activation code. After you add a key to the protected device, the license key is displayed in the application interface as a unique alphanumeric sequence.
The license key may be blocked by Kaspersky, if the terms of the End User License Agreement are violated. If the license key is blocked, add another license key for proper application operation.
A license key can be added as an active key or as a reserve key.
To extend the term of the application's main license, you can add a reserve key for the basic functionality. If you have activated additional functionality under a separate license, you can also add a reserve key for additional functionality.
A reserve license key can be added only if an active license key of the same type is already added.
A trial license key can only be added as an active license key. A trial license key or a subscription key cannot be added as a reserve license key.
