The Kaspersky applications installed on managed devices must be licensed by applying an activation code to each of the applications. You cannot use key files for licensing of managed applications; only activation codes are accepted. An activation code can be deployed in the following ways:
Kaspersky applications can use more than one license key at the same time. For example, Kaspersky Endpoint Security for Windows can use two license keys—one for Kaspersky Endpoint Security for Windows and one for activation of the Endpoint Detection and Response functions.
In addition, Kaspersky applications can have not only an active license key, but also a reserve license key. A Kaspersky application uses an active key at the current moment and stores a reserve key to apply after the active key expires. You can add a new active or reserve license key by any of the methods listed above. The application for which you add a license key defines whether the key is active or reserve. The key definition does not depend on the method that you use to add a new license key.
