Hi,
I am searching for a solution for registration problem.
I found your code in one of the thread.
Thanks for giving the solution.
OS in my machine is Win Xp and It is working fine. but on a machine having OS Win 98, it is returning 'Unknow' and not the HD Serial Number.
Can you please tell me if it will also work for other OS like Win 98 and Win 2000? If not, then which API can be used for that.
Thanks in Advance.

Regards,
Somesh
