Prevent forwarding of sent exe file

[mcatest]

I have developed a program in exe format & sell it on WWW.?
Is there a way to ensure that the buyer does not e-mail the exe file to a third person?


In other words, Is there a way to prevent the recipient of your exe file from forwarding it to a third person?
EXE file is installer of VB2008-created exe & other compiled files.


Thank you.

No there is no way you can stop someone from emailing something. You can however implement your own licensing system so that anyone who uses the software would need to have a valid license key and you could also make it so that they had to activate it online after they installed it so that you could verify only one person was using each license key.

Thank you. How would this be done? Is there a website where this is demonstrated, esp in VB 2008?

There are examples, but you'll really have to create your own. Examples get you so far before you realize that you're going to need something that you created to offer you the flexibility that you want.

No License System is perfect, but there are some good ones that cost plenty of $$$, or you can develop your own simple system instead.
