Hi found this when I was searching in despair for a way to use my Net MD Walkman NZ510 on my new Notebook with Windows7 home 64bit. I've downloaded the driver and unpacked it, but what then? In my device manager the player is recognized but need a driver so I put in the folder where the downloaded driver is but wouldn't recognized. I've seen just that others have modified the inf file but I don't know what lines to modify and where to save after. Is it going into the Windows/system32/driverstore folder? Sorry that I'm just a user with no much knowledge of these driver things. Hope you can help me, many thanks in advance!
