Linksys WMP300n drivers?

I'm trying to get this wireless card to work, and obviously, I need its drivers, however, the ones i downloaded from the linksys site is just an archive file with s bunch of dlls, 2 sys files, and 2 cat files.

How the hell do i install the drivers?

The card was aquired though second hand sales so i dont have the driver disc , and i had it working on another computer before but have forgotten how i did it.

Any help would be amazingly great because tech support wouldn't help due to it being out of warrenty -.-
