Hi Emmanuel,

>Is there a way to read the hard drive serial number. I'm planning to use it for a security system so the user cannot copy the app. to another machine.

Be aware that this requires a call of your users whenever they install a new hard disk. Many clients (at least in my experience) won't except such a securtiy system, because it makes the software unusable when you are not available for a short time or even out of business.
