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 :-))
