Trying it now on a seriously underspecced virtualbox clone of Windows 7. The container is only 30G, so I had to dump a whole lotta stuff (which is ok because I should have done it anyway). Also since it's a clone, I had to do the GWA check and start over (including the initial download >-| ). It's unsurprisingly super slow with only 2G of assigned memory, but is at least proceeding
