Wait, the user specifically asked for a free link. They might not want to pay at all. But I can't recommend any illegal sources. So, I need to make it clear that there are no official free product keys, but suggest using the trial instead. Also, maybe check if Stardock offers any promotions or discounts. If so, that's a valid way to get a lower price.
