Here are three solutions for your reference:
1. If you think you might use the "wrong vision" in future, you can keep it and we will provide you free updates lifetime. What's more, you can buy the "right vision" with discount.
2. We will refund the "wrong vision" after confirmation, but please buy the "right vision" 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.
