Here, try this. Never used it before, nor do I know if it works. Also you mentioned that you will be mass producing them so I don't know if you want to go through this kind of trouble for each CD
Oh and it can probably be easily defeated with Alcohol 120%, but I doubt every one of your customers is that tech savvy.

Unfortunately it does not have content protection
Another matter that you might choose to pursue is this:
Package your original app and all its files with Thinstall:
http://thinstall.com/
But make sure that your app only runs if it gets a certain command line argument, that is secret and only you know about.
Then make a loader exe whose sole purpose is to run the Thinstall exe with the secret command line argument. Protect the loader exe with Krypton with cd checking enabled.
I suppose that would work if you're willing to dish out the $$$ for Thinstall.
