I intigrated with Nlite no problem until I tested with Virtual Box.  It was asking for WINNTBBU.DLL from i386. I checked the source and it was there but after integration it was missing.  Tried a few times with the same result.  Did the install just to see how it would go.  There was a update for ie7 that could not be installed.  Also WMP11 turned out to be WMP9. I'm still trying to figure it out and looking for answers.
