I had (still not come behind) the problem for some reason not be able to install network adapter drivers under Win 7 Ultimate 64 bit. From desperation ordered the CD, honestly no big Erfolgsausicheten, but the fact that I now write this proves the opposite :) Just CD thrown in, start scanning and the rest went virtually by itself. Whether you really all the drivers on the CD gets I can not say but for the little money it is worthwhile in any case, a lot of stress to spare. As an IT system merchant because you can only give it two thumbs up: D
