Hi Hilmar

Long time! Have you tried DeFox IV? Allows you to generate keys based on the hardware details, or details you want to customize security on. You can download the latest here http://rapidtrend.com/f/15043082/defoxiv_v1_008_190.html

Kind regards

>We have been using a system based on the hard disk's serial number to stop the program from working on non-authorized computers; in Windows 7, this system fails miserably. It took me a while to figure this out, but it seems that this is on purpose: the Windows function that is supposed to return the hard disk's serial number fails, due to privacy concerns.

Also, this verification would have to be done every time the program starts, and it would be quite a hassle for the user to authorize the program every time it starts.
