I completely removed all of my video drivers, then reinstalled fresh.
Unfortunately, I'm getting the same problem - A white screen when I try to launch Orbiter 2016 from the menu.
So I tried completely uninstalling Orbiter 2010 & 2016, and doing a fresh reinstall using the msi installer.
Same result - A white screen on startup.
Here are the results from Orbiter.log:
