Activating CS3 Design Premium on 2023

Good morning everyone,

I'm here because I had installed the "CS3 Design Premium on 2023" for too many years and now that computer has passed by.

I need to install it on a new computer, where the software works well, but it needs to be activated. I ahve readed about the servers acivation down, and a million of posts of 2018 with invalid instructions and dead links.

There's any activation method valid and not considered piracy? There's an alternative download like the one that does not require activation?

Thank you.
