Thank you for your message.
Could you please clarify if the Host startup mode is set to auto or manual? You can check it in the Host settings on the Service state
Also, please try to start the Host manually:
1. In the Windows search box type "Start Host".
2. Click Start Host in the search results.
Then check if rfusclient.exe
are present in the list of processes on the Host PC.
For more information on rfusclient.exe and rutserv.exe please refer to this KB article
In addition, please clarify if the Host PC was restarted after the installation?
Looking forward to your reply.
