Installing XAMPP, the control panel eventually said that Port 80 was in use by "unable to to open process" with PID4. I don't know how to unblock this port. Alternatively, I don't know how to induce XAMPP to use another port. I clicked the "config" button and then the "service and ports" button which referred me to config files. But I don't know my way round well enough.
I bet there is an FAQ dealing with this somewhere on the forum, but I can't find that either ! (bumbling twerp
)
