i can't remember if i remarked that this will hit the registry, so maybe it,
too, needs to be done on the FILE thread.  won't this cause a DCHECK in the
thread checker thingamaboob?

It does. I just didn't see it because I built mini_installer in release so that
I didn't have to setup all the debug runtimes in order to test it on a clean VM
machine. Fixed.
