ASUS computers include a utility called “Sonic Suite 2”; a third-party tool authored by “Volute”, for on-screen tools for audio functions.
On ASUS computers running single monitors, it seems to work fine.
On some ASUS computers running extra monitors, Rhino may not start because of this utility.
The fix is to uninstall this troublesome tool.
In Control Panel, Programs and Features, find:
ProductDaemonSetup and is installed by ASUSTeKcomputer
and remove it.
Since it is a running Windows Service, you may have to restart Windows.
Then Rhino should start.
