I bought Gal 1&2 steam version, but where is my 1's cd key?

cd key is required when logining in metaverse,  I can find my Galciv 2's key just like other steam games, but there is no cd key tab on Galciv 1,  I googled some post, said: when installation completed, key will be provided by steam , but I don't see any popup window, and even I start game, still no cd key notification

I have submitted tickets to steam & stardock support, but no reply till now, anyone know where is 1's key? or is it a bug on steam version now?
