I should start by addressing the illegality of keygens and stress the importance of using authorized software. Offer support in case they have a license but need help with activation. Suggest purchasing a license if they don't have one. Also, provide steps they can take to resolve activation issues through official channels. Make sure the tone is helpful and respectful, not judgmental. Avoid any mention of actual keygen creation or distribution. Check for any possible misunderstandings and clarify that Delphi versions might be confusing them. Maybe they confused the version number. Offer to help with the correct version if that's the case. Ensure that the post is clear and guides them towards the right path without enabling piracy.
