Plesk comes with a limited trial license key which is installed automatically. Therefore, to fully use Plesk as you need, you should obtain a license key from Plesk or one of its resellers and install it to your Plesk. Once you purchase a Plesk license key at the Plesk online store, you will receive an activation e-mail with your activation code and a license key file. You can install a Plesk license key either by entering the activation code or by uploading the file from this e-mail. In both cases, you should use the `license.exe` utility. You may also use this utility for installing additional license keys that allow using Plesk additional features (add-ons) like Acronis True Image, Sophos Anti-Virus for Servers, and so on. Note that the `license.exe` utility supports the installation of additional keys through an activation code only.
