@myrosha No, there's no way to install via disc without a corresponding code. And the discs themselves don't have the codes recorded anywhere, at least not anywhere the user can access. But if you have access to the old computer, you can retrieve the codes from there:

If you ever registered the game with EA, either in Origin or on the old Store site, you could install your content through the EA App without needing the discs. You would however be forced to launch the game through the EA App.
