Installing Plesk for Windows in Unattended Mode

--source <URL>

or

--source <PATH>

Packages source options define the location where the installer
should obtain the Plesk packages for installation. You can use
either --source <URL> to specify the URL of a mirror of the
Plesk updates server, or --source <PATH> if the packages
are found locally on the file system. If you use neither, the
Plesk packages will be retrieved from the Plesk updates server.

For information on managing local mirror repositories, see
Mirroring Plesk Autoinstall Servers.

This option defines what Plesk version will be installed. <ID>
is a unique Plesk version identifier (e.g. PANEL_17_0_17_WIN).
