I am having trouble updating Host from version 7.1.6 to 7.6.2, and when I uninstalled and then reinstalled, I encountered a fatal error: rfusclient.exe is corrupted.
The steps I have already taken are:
- Updated to KB5037768.
- Excluded the following paths from my antivirus software: C:\Program Files (x86)\Remote Utilities - Host\rutserv.exe and C:\Program Files (x86)\Remote Utilities - Host\rfusclient.exe.
- Performed a clean uninstall (deleted the registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Usoris) and then attempted to install RU Host version 7.6.2, but the fatal error still occurred.
However, when I revert to installing version 7.1.6, I do not encounter the error.
host version 7.6.2.msi that I use I downloaded from the official web and tested it installed on another machine and it works fine.
Do I need to perform any further updates or steps?
P.S. This PC is designated for my system testing. Please advise.
