"Couldn't switch to requested monitor resolution
Switching to resolution 800x600 failed, trying a lower one
All resolution switches have failed
Screen: DX11 could not switch resolution (800x600 fs=0 hz=0"

That's the message I get when I try to start the launcher on my windows 7 machine.
It's x64 and the lowest resolution it has is 800x600 which it is set to by default.

Anyone know what's going on?

An update will be in within the next few hours that should resolve this problem Emperor. Will keep you posted.

The new patch is live Emperor. There is support for more resolution values, including the one you've had problems with. Let us know if this is resolved after you patch up.
