This is a way around that will keep most user to suspect anything if the files are names wisely. Good idea. Thank you.

But still, the reason I asked that is because I use this application as a demo. This demo is available to my possible clients that want to evaluate our software. This is why I don't want them to print because they will be able to use it whitout buying it. Sure I have other protection that will protect my application but this is the only one that tickles me.
