Vostro 1500 Bluetooth Driver install error

Hello there.  I have a Vostro 1500 running Windows 7 (shipped with Vista) that has a built-in bluetooth adapter.  The problem is, while the device comes up in the system setup, it is absent from the Device Manager list.  

Naturally, I tried to install the latest driver for the device.  Unfortunately, when I try to install it, even after right clicking to Run as Administrator, I am informed I "don't have sufficient privileges to complete this installation for all users of the machine ."

This is being attempted with the only account on the machine, which is naturally the owner and administrator, so I am quite confused.  Does anyone have any insight here?  Thanks.
