- the viewer runs on Windows-7 - the client ('host') runs on Windows-10 - I can properly make a connection from the viewer to the host, altough the screen on viewer remains black - when I move the cursor on the 'viewer' PC, I see the cursor also moving on the 'host' PC - so the connectivity is fine, only the display does not get through
Maybe irrelevant, but the 'host' PC is a Full-HD monitor, whereas the 'viewer' PC is a more conservative monitor. I tried already to lower the resolution of the 'host' PC monitor to the same resolution that the 'viewer' PC has, but this doesn't help.
Both PC's are entirely up-to-date with regards to graphics drivers etc.
We run BitDefender antivirus, and I have added the executable "rutserv.exe" on the host to the list of excluded processes in BitDefender : no change.
I have other 'host' PCs, running Windows-7, and they all are correctly accessible and visible from the 'viewer' PC.
I see. Before we try to diagnose I recommend that you install the latest beta, you can take it from here https://www.remoteutilities.com/download/beta.php . If it's a bug, it well may have been already fixed in the beta. If the problem persists even with the beta, we'll see further what it might be.
Please, make sure that you upgrade both parts - i.e. Viewer and Host - to avoid version mismatch.
