So the big question is - "does it JUST need to be displayed", or "does it need to be displayed & clicked on".
If it just needs to be DISPLAYED, then installing it as "some admin user" should work fine (Sure, Windows will display it in a user session that no one will see, but that doesn't matter really). If it needs some kind of clicking ... then you're in a spot of trouble - because your end-users lack the admin rights & the way that Windows handles user sessions makes it impossible for us to run it "as an admin" and yet display the GUI to the end-user.
