Can't install RC2:

[Guest]

So after a few hours of updating my RC1 install to RC2, it gets all the way
to the Finishing Install step when it reboots a few times (which is normal)
and then I get a window popping up that there was an error and my previous
install with be active again. I can't seem to update RC1 to RC2 at all right
now. Tried it twice.

In that case I'd ask that you try a clean install of RC2.
