First, You should add:

Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException);

After that You can catch exceptions, for example:

[STAThread]
    static void Main()
    {

        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException);
        Application.ThreadException += ApplicationThreadException;
        AppDomain.CurrentDomain.UnhandledException += CurrentDomainOnUnhandledException;

        if (DataBaseMNG.Init())
        {
            Application.Run(new MainForm());
        }
    }

    /// <summary>
    /// Global exceptions in Non User Interfarce(other thread) antipicated error
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    private static void CurrentDomainOnUnhandledException(object sender, UnhandledExceptionEventArgs e)
    {
        var message =
            String.Format(
                "Sorry, something went wrong.\r\n" + "{0}\r\n" + "{1}\r\n" + "please contact support.",
                ((Exception)e.ExceptionObject).Message, ((Exception)e.ExceptionObject).StackTrace);
        MessageBox.Show(message, @"Unexpected error");
    }

    /// <summary>
    /// Global exceptions in User Interfarce antipicated error
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    private static void ApplicationThreadException(object sender, ThreadExceptionEventArgs e)
    {
        var message =
            String.Format(
                "Sorry, something went wrong.\r\n" + "{0}\r\n" + "{1}\r\n" + "please contact support.",
                e.Exception.Message, e.Exception.StackTrace);
        MessageBox.Show(message, @"Unexpected error");
    }
