Hi Homer49, I've been told that a lot of them are not compatible with 64bit so rather than get the wrong one I rang Unikon who told me that they would send me one and to download a driver for it off their website, but it has not arrived yet. Just wondering what types are being used by members on here who are running windows 7 (64bits). The adapter we used when running windows xp is not compatible for windows 7. cheers Stuart
