    In the .NET Framework 1.0 and 1.1 there is no way to catch this exception
    because it occurs outside the scope of your application. When you perform a
    RequestMinimum, you are basically telling the CLR not to start your
    application if it is not granted the permissions that you specified. As
    such, there is no way for your app to catch the exception because it is not
    even allowed to execute. Anytime your app generates a PolicyException, you
    will have this problem.
