I have Max Payne 2 -- where's the key for Steam?

[bupkus]

I bought Max Payne 2 way back so I have the discs and original packaging, but I'm looking for the key. Is there one or is the possession of disc 1 all I was supposed to need?

I want to add to my list of Steam games but I've never done that except buying from Steam.

It can't be activated on Steam. You can add it as a non-Steam game, but most games (at least older games) cannot be registered with Steam.

There's a list here: https://support.steampowered.com/kb_article.php?ref=7480-wusf-3601#which

I just installed MP2 and it doesn't require a key to play, just disc 2.
Installing on Steam is only a launch link on my list of games.
It does seem to play ok on Windows 7, but I think I'll just give it away. I'm just not into gaming much anymore.
Too bad, I just bought Portal 2 and really don't feel like playing it. Perhaps later this winter.
