This topic seems to have appeared before but look related to the Channels DVR service not running.
Mine is running ok but I get the Error anyway.
The service is running on the local system account.
Could there be access rights in relation to the local system account ?

Are you running as a service or in the system tray?
When do you see this error?
It is running as a service.
The error occurs on windows start up or probably due to channels start together with windows
You can remove channels dvr from autorun if its setup as a service. It's trying to do both and causing that error on boot.
