Create a Solution activation task for the Protection Server. The task scope must include the SVMs on which you want to activate the solution.
When creating a task, use the main solution license key added to the Kaspersky Security Center key storage. You can add a license key to the Kaspersky Security Center key storage in advance or when creating an activation task.
Run the Solution activation task and make sure that the task completed successfully.
If you add an active key, the task activates the solution on those SVMs on which an active key was missing. On SVMs on which the solution is already activated, the task replaces the old key with the new one.
If the number of licensing units for which the key is used exceeds the number specified in the License Certificate, Kaspersky Security sends the Kaspersky Security Center Administration Server an event indicating a violation of license restrictions (for more information, refer to the Kaspersky Security Center Help of the relevant version).
If the main license under which you have activated the solution does not include the additional Light Agent functionality that you need, you need to create and run another activation task. When creating this task, use a license key that provides the additional functionality. Adding a key that provides the additional functionality is no different from adding the main license key for the solution.
Make sure that Light Agents are connected to the SVMs to which you added the license key.
