To add or remove Plesk components, go to **Tools & Settings** \> **Updates**. When you select **Add/Remove Components**, you will be asked to provide system user credentials to proceed.
Note You need to provide system user credentials, not those used to log in to Plesk. The user in question also must have the necessary permissions to install software. The administrator credentials you use to log in to the server via RDP should work fine here.
