I need to structure the response. Start with a note on legality, then mention the risks of using cracked software. Offer alternatives like trials or educational licenses. Maybe also suggest other free CAD software if they can't use CATIA specifically. Make sure the tone is helpful and not accusatory.

First, I need to consider legal implications. Providing or sharing cracked software is illegal and violates copyright laws. I should make sure the user is aware of that. Maybe they're trying to use CATIA but can't afford the license, or they don't know where to get it legally.

Also, the user might not be aware of the risks involved with cracked software—malware, security holes. It's important to mention those. If they download a crack, their system could be compromised.

Let me make sure I don't provide any links or instructions. Only warn against it and offer legal options. Use clear, straightforward language. Avoid technical jargon so it's accessible.

Next, I should check if there are any legal alternatives. Dassault Systèmes offers trials. Maybe suggesting a free trial or educational license if they're a student. That's a better solution than finding a crack.

Wait, the user might have a legitimate need but just not know where to get it. So focusing on legal pathways is key. Also, emphasizing that supporting developers through purchasing licenses helps improve the software.
