OK, I have it running.
My configuration in my Home Theater is that I'm using my AVR --> LG TV as the second monitor, allowing me to run REW, etc.
I shut down the AV system, reran IoX launcher and the Admin Console app runs. It came up in the 2nd monitor space which I couldn't see so I moved it over to the main monitor.
I guess this is a Windows issue, does this make sense to anyone?
Thanks for the troubleshooting ideas.
