Hello,

I need to create an installation program that has two modes: register and demo mode. In register mode, the user will input their code and have full access to the software after purchasing a license. In the demo mode, the user will have limited usage and once the user has exceed the usage "count" disable functionality to use the program.

I don't know where to begin to see what are my options. How do I prevent users from
circumventing once the count has been met? What is a good resource to read about the different options?

thanks,

you can take a look at the shareware starter kit:

I have not used it but I believe this will be the one you are after in terms of creating a registration type program for your application.

Is there a non .Net solution as well?

The functionality of the Local Data Store is what I am seeking for.
