Hello Armin,
A question: Are you updating an existing installation with your custom Host package, or is it a new installation on that PC? That is, no Host was previously installed.
But my ID-Server doesn't see any new devices. Ok, i stopped the service and ran the exe by hand to check its settings. All settings are reverted to default - this means, standard ID-Server is used, no saved passwords etc...
You can simply run Settings for Host from the Windows Start menu.
