PS: According to the user guide

that drive is 'plug & play' anyway. (i.e. it uses drivers that are built into Windows, without the need to install any new drivers).
Are you thinking of the Lightscribe software ie, the software required to produce Lightscribe labels as opposed to the drivers needed to operate the drive as a DVD writer? As Buenchico says, the drive is "Plug and Play", so the drivers should take care of themselves.
If so, have a look here
