### Installing Additional License Keys for Plesk Add-ons

To install an additional license key for an add-on Plesk component:

1. Click the Server shortcut in the navigation pane.
2. Click the License Management icon in the System group.
3. Click Order Control Panel Add-Ons.
4. The SWsoft online store page listing available add-ons will open in a separate browser window. On this page, select the add-ons you want to order and click Submit.
5. Because Plesk add-ons are added to the license keys that already exist, the Plesk Number Checking System page will open. Enter the number of your license key to which you add this feature and click Submit.
6. In the next steps, indicate the currency, number of keys, provide contact details, billing address, and payment method, and submit the form. You will be notified by e-mail when your order is processed.
7. When you receive the e-mail notification, return to the License Management screen (Server > License Management) and click Retrieve Keys to retrieve the ordered license key. Plesk License Manager will retrieve the upgraded license key from the SWsoft licensing server and automatically install it to your control panel.
