About application activation

Application Activation is the procedure to activate the license and receive the right to use the fully-functional version of the application during the course of the license term.

The application must be activated on an SVM with the current system date and time. If the system date and time are changed after activation of the application, the key becomes void. The application switches to a mode of operation without database updates, and Kaspersky Security Network is unavailable. In this case, you need to redeploy the SVM and activate the application on the SVM.

To activate the application, a key must be added to all SVMs.

The application activation task is used to add a key to SVM. The activation task allows you to add a key that is stored in Kaspersky Security Center key storage of to the SVM. You can add a key to Kaspersky Security Center key storage while creating an activation task, or in advance.

You can add a key to the Kaspersky Security Center key storage in one of the following ways:

• Using the key file
• Using the activation code

After the application has been activated on SVMs, the Protection Server component relays license info to the Light Agent component that is installed on the protected virtual machines. If the key status changes, the SVM sends the relevant information to Light Agent.

Information about the license under which the application has been activated can be viewed on the protected virtual machine:

• For Light Agent for Windows – in the local interface of Light Agent for Windows in the Licensing window.
• For Light Agent for Linux – using the license command.

Information about keys added to the SVM can be viewed in the Kaspersky Security Center Administration Console or in the Web Console.

If license info is not relayed to the protected virtual machine hosting the Light Agent for Windows component, Light Agent for Windows runs in limited functionality mode:

• Only the File Anti-Virus and Firewall components of Light Agent are available.
• Only the Full Scan, Custom Scan, and Critical Areas Scan tasks are performed.
• Databases and application modules required for the operation of Light Agent are updated only once.

If license info is not relayed to the protected virtual machine hosting the Light Agent for Linux component, Light Agent for Linux runs in limited functionality mode: application databases required for the operation of Light Agent are updated only once.

If your infrastructure includes several instances of Kaspersky Security administered by several Kaspersky Security Center Administration Servers that are not combined into one hierarchy, you can activate different instances of Kaspersky Security by adding the same key. A key previously added to an SVM administered by a single Kaspersky Security Center Administration Server can be added to an SVM administered by a different Kaspersky Security Center Administration Server if the validity period of the license linked to the key has not expired.

When license restrictions are checked, the total number of licensing units on which the key is used on all Kaspersky Security Center Administration Servers is taken into account.

To use a previously added key without violating licensing restrictions:

1. Remove SVMs on which the application has been activated using this key on the same Kaspersky Security Center Administration Server.
2. Create and run an application activation task on a different Kaspersky Security Center Administration Server. A key added to the Kaspersky Security Center key storage can be exported in advance from one Kaspersky Security Center Administration Server to another Administration Server (see the Kaspersky Security Center help for details).
