I had 409.1 workin on vista running under xp compatabity. Now doesnt work. Iv ordered another cable. Going to try using it on windows 7. Must be a way. After they launched new software seems to not work unless genuine cabe is used 
Will prob need xp emulator on the windows 7 laptop i got.
Just install windows XP on your windows 7 computer, i'm running mac os, linux and xp on my windows 7 laptop!
Install XP, install vagcom and the drivers
