Controls on 'software' transfer only apply where specifically indicated in sections I and II above, and do not apply to 'software' which is either:

  1. Generally available to the public by being:
    1. Sold from stock at retail selling points without restriction, by means of:
      1. Over-the-counter transactions;
      2. Mail order transactions;
