So, my response should clarify the version number confusion and inform the user about the correct version. Then, I must emphasize the importance of purchasing licenses legally. Maybe suggest where they can buy it or find genuine versions. Also, if they have a license but lost the serial, offer to check their account for the serial number. Need to make sure the post is helpful but doesn't endorse piracy. Should I mention the legal consequences? Maybe not too harshly, but enough to make them realize it's against the law. Also, perhaps recommend free alternatives if they're looking for a budget-friendly option. Let me structure this step by step.
