Bought this game 2004, activate on steam?

[heh]

Hey guys, it´s not very active here but maybe one of you can help me :)
As the title says, I bought this game 9 years ago in a nice big box, it has 2 CDs, a manual with almost 100 pages and a very beautiful huge map with the KoH-world on one side and all the buildings, units etc. in the other side :D
Now the question is, as you might guess, can I somehow activate it on steam?
It does not actually have a CD-key, you only need the CD in your CD-drive to play it after installing.
Without a CD-key there is probably no chance, but maybe one of you had the same experience and somehow managed to activate it.

Even with a CD key, you probably wont have a chance of activating it.
I bought the game on steam, even though my friend got it.

Just buy it on steam, its not that expensive and it gives you the latest update(s).

you cant activate it on steam.

You bought it fom a different store and not from steam, so they cant just let you download it from their servers etc. Only very few games have a special contract with steam and have their store versions activate on steam.

I have both discs right in front of me right now, crusader: no remorse too (random and irrelevant i know haha) Lost the manual but definitely have the cds. I imagine you can only add it as a "non-steam" game.
