Unfortunately this does not work if the user is a "Standard User"... 
instead of the dialog with Cancel and Allow, you need to enter an 
administrator's password. You can *still* write the file into the 
Program Files folder and not have it virtualized, but it makes it 
difficult for non-Administrator-level user to get updates this way... 

Vista's a real PITA!
