Activating the game on different operating systems. Auto-translated

I reinstalled the system, reinstalled Heroes cleanly from the disc, downloaded all the patches through the Ubisoft launcher, and entered my Uplay account details. Then, it asked for a key. When I entered the key, I received the message "key already used." The logic seems to be there – new Windows, new computer – but is it normal that the key isn't linked to the account? And what should I do now? Buy a new license?

I found a similar question on the internet, but it remained unanswered. I'm counting on you, forum members! What should I do?

That’s strange. I installed the game on different computers; after reinstalling and entering my login and password, it no longer asked for the key.

Problem solved: I was an idiot. It turns out I had two accounts on the forum, and I was entering the login details for the other one. I have no idea when I managed to create a second account... I just have two standard usernames and one standard password. I tried the second username out of curiosity, and it turned out that there were indeed two accounts. That's what happened. Sorry for the inconvenience, please delete the thread.
