You can download the drivers themselves but this thing does it all for you.
All the way at the right hand side, under comments, you'll see 'setup executable'. Since we're doing windows, I'm only covering that. Go to and scroll down to the box with listing of drivers of different operating systems. It'll attempt to find the driver and succeed, or not. Wait like 5 seconds (not 100% you even need to wait the 5 sec). After you're done, plug the scanner into your OBD2 port, without having it plugged into your computer. Go ahead and install the bmw scanner software.
After reading through many of them, they only provide partial instructions, instructions even myself, an expert (on a scale between novice, advanced, expert, master) computer user struggled, that is for a few hours. I have noticed that some people are having quite a bit of trouble installing this on the 64bit side, even though there are already threads telling them how. I have tried it on windows 7 home premium 64 bit, as well as windows 7 ultimate 64 bit. I am in no way responsible for any damages caused to you, or your car, or your bmw scanner for any of this. Edit: Oh yeah, in case you're all wondering.
