Plesk Components
You can select what Plesk components will be installed. For additional information about Plesk components and extensions, refer to Plesk documentation.
Depending on the selected operating system, different components and hosting features are available for installation.
Some Plesk components may require the additional component's license to be installed. If you have configured the automatic generation of Plesk licenses, then the system will also automatically issue any additional licenses for the selected components that require them.
