When I open either the computer manage screen or the device manager screen you can no longer access anything. I tried closing the connection and opening it again and we have the same thing. No matter what I click on has no effect as if the computer was frozen. When I call the client to close the screen all works fine.
Also tried to run the msi installs to no avail. Don't get an error - nothing gets installed. Had to install it manually from zip file for the viewer and let the client just fownload the exe file and launch it
If you want complete control over the remote computer including the ability to control UAC prompts and install applications, you should use Host instead of Agent. Unlike Agent, the Host works as a system service with system-wide privileges.
