Are you running VoiceAttack itself as administrator?
I was not running as admin, but here is what seems to have happened after more testing.
parameters requires space before the '/' in order to run this parameter /RUN /TN "UAC White\Sim Commander 4 UAC enabled"
So it seems the path is correct and I only needed to ad a space before the /RUN in order to execute property.
I still can't seem to get any application to open using the options such as normal, minimized, maximized, hiddent etc.
There does not seem to be any change in the window for these option selections.
Thanks
