Here are two solutions for your reference:
1. If you think you might use the "wrong product" in future, you can keep it and we will provide you free updates lifetime. What's more, you can buy the "right product" with discount.
2. We will refund the "wrong product" after confirmation, but please buy the "right product" first.
Note: As our product is virtual software, once we sent we can't get back the registration code. And we also do not know whether customer use registration code or not. So if customer insists on refund, we will deduct 20% of the purchased price as fee. Thank you for your understanding.
