Additional Information:
When installing TightVNC Server, the Prerequisites for Windows Robots UiPath documentation says "Make sure that the Register TightVNC Server as a system service option (under TightVNC Service configuration) is not selected".
Note that in UiPath implementation, the VNC server is not installed as a Windows service because each user spins up their own type of VNC instance, contrary to the typical server installation.
