Not sure the released APU drivers will work on a Windows 7 machine.

You may already have these drivers and the main issue is that you are running Windows 7 and they are not compatible.

Regardless, if I were you....

you are probably better off to use a machine running Windows XP if you can.

Keep me posted on your progress.

Kind Regards,
