Install remote client only on Windows and Macs

I let the roon client update itself on this old laptop I’ve been discussing, where I only want to have the client installed.

When I turned on this computer, a windows firewall warning came up, asking me whether or not to grant external network access to RAATserver. Why is this program/service even starting up and triggering this firewall exception request?

This is a problem. A program I don’t want installed on my computer is requesting access to the internet. This is another reason to allow for client-only installs on windows.
