        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            string DispalyName = null;
            string RegistryKey = @"SOFTWARE\Microsoft\Windows\CurrentVersion\UnInstall";

            DataTable dt = new DataTable();
            dt.Columns.Add("Software Name", typeof(string));
            dt.Columns.Add("Software Version", typeof(string));
            dt.Columns.Add("Software Publicher", typeof(string));
            DataRow dr = null;

            using (RegistryKey RegistryKey1 = Registry.LocalMachine.OpenSubKey(RegistryKey))
            {
