Yes, Pauline, I have AV software installed on all of my computers but it is not interfering with RU in any way. This is clearly a host software issue. Both host computers are reporting the same fatal error.
Sorry to report that the fatal error is back. It was a good run, almost a full 24 hours! This morning when I tried to connect to the same host, that was working last night, the same error came on the host and I cannot connect. I also upgraded my other host computer to the 188.8.131.52 and I cannot connect to it. The owner of the host is not available yet to advise if they have the same error screen.
Okay, this is where I am. I performed a complete removal of both the viewer and the host. (including removing traces of the program fr om the registry). I then did a new download and install of the 184.108.40.206 version of each. I created a new Internet ID and and a new connection on my viewer and attempted to connect. This is the only place wh ere I receive any errors. As soon as I try to connect, the Host computer gives the "fatal error: rfusclient.exe not found" The Viewer computer shows no errors and just continues to show the "Connecting to HOST" screen. I can connect to the only other host I have in my address book but that host has not yet been upgraded to 220.127.116.11. This brings me to the conclusion that there is a glitch in the new Host version.
Thanks for the info Pauline. I tried the tool and the response was that the problem was fixed but I'm still getting the rfusclient.exe not found fatal error. Please note that I don't have a problem installing or uninstalling the RU host. It's only when I try to connect to the host from my viewer (both running 18.104.22.168 on Windows 10) using either the ID number or using the direct connection with both computers connected to the same WiFi
Both Viewer and Host version 22.214.171.124 on Windows 10 After update from 126.96.36.199 my host will not connect and I get the fatal error message. I have run Microsoft .NET Framework Repair Tool and done a complete reinstall (3 times) of Host as per the guide on this platform.
