        int period = 30; // trial period

        string keyName = "Software\\Rano\\SomeApp";

        long ticks = DateTime.Today.Ticks;

  
  

        RegistryKey rootKey = Registry.CurrentUser;

        RegistryKey regKey = rootKey.OpenSubKey(keyName);

        if (regKey == null) // first time app has been used

        {

           regKey = rootKey.CreateSubKey(keyName);

           long expiry = DateTime.Today.AddDays(period).Ticks;

           regKey.SetValue("expiry", expiry, RegistryValueKind.QWord);
