From what I know of these things 3d, that Bluetooth push-in thingy is the critical bit - without it (and assuming your laptop doesn't have an internal one) you can't "do" Bluetooth. It'd be like using a 2-way without the aerial connected. As the link u posted has "driver" in it, I'm assuming that's a driver rather than an app, which if that's the case, still won't solve your problem as drivers are the "language" used by the laptop to talk to your Bluetooth dongle (the push in bit).
Hope that helps... ...sort of.
