At this point why isn't an upgrade performed, as there is no other option and the GUI does that. I don't see the point in informing the user an uninstall is required, just ask to proceed and do it.

But anyway if I then do ...
{{{

So can't ""upgrade"". BTW I have tried without --forced first, but that didn't work either.",defect,closed,host support,VirtualBox 4.0.10,fixed,extpack vboxmanage,,Windows,Linux
