I'm agree with you and Cetin, but We must do something to control the application.
I will explain to you briefly why we needed to do this:

We sold to a multinational insurance company a software that they distribute it among their insurance brokers. The insurance company have offices in all Latin America and the contract is only for few countries

How can we are sure that the insurance company will not distribute the software in another countries?
As first solution, We thought that our software will run only with a previous control of regional settings.
We know that it is not the definite solution, but we are approaching

Regards

>Ricardo,
>Cetin is right. Regional settings are not the indicator where your application runs.
>Most people set their regional Settings, but you need ONE that is not and all protection blows.
>For testing pourposes I change my Regional settings twice a day :-) You see, that if your application runs with some regional settings but doesn't run with others what will be my next step :-)
>But I have one question: WHY? Why you don't want your application to be used in that countries? (this is just a rethorical question, I can't tell you where you'll put your furniture :-))
