When launching sessions as a host using the urllaunch app installed on the PC the user.config settings XML file is stored in C:\programdata\ScreenConnect Client(thumbprint) folder. This is fine for most cases however if using on a terminal server or a shared PC where multiple users log in then the users all share that same settings file.
Currently the workaround is to force ClickOnce use that way the settings are stored on a per user basis. Please consider changing how the client application stores the user.config setting.
