It means that wpa_cli did not find running wpa_supplicant process that
had enabled the control interface.

As far as using wpa_cli or wpa_gui is concerned, you will need to
include ctrl_interface=udp in the configuration file. Other than that,
there are no additional requirements.

It should be possible to do it either way, but in most cases, I would
recommend starting wpa_supplicant first.

README-Windows.txt has some information a bout using wpa_cli and how to
configure ctrl_interface, but admittedly, there is no thorough end-user
type documentation for this yet.
