When I try to start the Capture One Pilot server I get the message "Capture One Pilot Server failed to start. The Capture One Pilot server was unable to start, most likely because the bonjour service component is missing. Try to reinstall Capture One".
First of all, make sure that BonJour service is installed on your computer (it is usually installed as a part of iTunes).
Also, make sure that the version you have installed is up to date via the updater.
The minimum requirement is the version 2.0.4 (installed as part of Apple updater).
