Service can't start with error 1067

UrBackup Client 2.4.10 (x86/x64) (Vista/7/8.1/10 + Server editions) without tray icon doesn’t work on Hyper-V Server 2012 R2 (“ServerHyperCore”, build 6.3.9600.16497) , throwing error 1067 whenever starting the service. It must be noted that VMs are not the target, but rather the files on hypervisor FS.

You have set it to internet only mode but haven’t configured an internet server.

Thanks, copying settings.cfg with modified variables did the trick. Could error definition be expanded in later versions though? Because current wording of the message suggested that either Windows edition had critical components missing, or client backend didn’t ingest config file properly.
