Install Client Access Licenses

In this task, you install and register the client access license (CAL) pack that is included with your edition of Windows EBS. This is a Standard Edition or a Premium Edition 5-pack. You can also install additional CAL packs that you purchased.


To install each CAL pack, you must have the 25-character CAL pack product key. This key is different from the product keys for Windows EBS.

Before you can install CAL packs, you must complete the following task:

Activate the Servers

To install a CAL pack

  1. In the Configuration and Migration Tasks checklist, click Install client access licenses, and then click Start Install CAL Packs Wizard. The Install CAL Packs Wizard appears.

  2. On the Before you begin page, click Next.

  3. Read the Client Access License Agreement. If you agree with the terms, click I agree, and then click Next.

  4. On the Add CAL pack keys page, type the product key in the Product key text box, and then click Add. The key and information about the CAL pack appears in the text box.

    If you are installing more than one CAL pack, repeat this step until you add all of the CAL pack product keys, and then click Next.

  5. On the Summary page, verify that the information for the CAL packs is correct, and then click Install.

  6. The Installing CAL packs page appears. Then the Finish page appears, and you can review the details of the successfully installed CALs.

  7. Click Close to close the wizard.

Additional considerations

  • After you install a CAL pack, you can assign CALs to specific user accounts or devices. To access the Windows EBS network services, a user must have a licensed user account or log on from a licensed device.
  • To install additional CAL packs at a later date, start the Install CAL Packs Wizard from the Windows EBS Administration Console: Click the Licenses tab, and then on the tasks pane, click Install CAL packs.
