Right after the installation, Plesk uses a trial license key. To get a paid license key, go to the Plesk online store (shop.plesk.com), select, and then purchase a necessary license key.

Once you purchase the key, you will receive an activation email with your activation code.

Per installare una chiave di licenza usando un codice di attivazione:

  1. Go to Tools & Settings > License Management (under «Plesk») and click Install Key.
  2. Enter the code you received in the email to the «Enter an activation code» field and click OK.
