Hi friends,
I have an add-in which I want to protect from piracy.

Can I somehow write a code in Auto_Open that will access the registry entry and will verify if the installation is genuine..

I have an installer that on installation adds few details in the registry and also installs the add-in on clients machine. I just need a code to be used in 'add-in' so that it cannot be distributed illegally..

I hope I am able to explain my problem.. If there is anything more you need about it please let me know..

Regards,
Vaibhav
