I have lost my cd key to install Civ 4 and have since purchased the steam version. But I have an extra key still installed on Windows XP. How can I retrieve the key from my registry and where? And how can I have steam respect both licenses so I can play against myself, with my steam license and the license from my retrieved key?
 
If you can play your store-bought copy on the machine that it's installed on, then install the Steam copy on a different machine. Right?
 
Correct. Thanks for the replies.

But Civ IV is installed on a Windows XP installation on my desktop. I want to wipe the installation of Windows XP to leave more hard drive space for windows 7. If I can get the key out of the registry, wherever it is, I can wipe the Windows XP installation for good and install my legal copy on any computer I want, and play against my legal steam version on any computer I want.

Thanks for reading through this - any idea where to find the CD key in the XP registry?
 
As ori has said, there is no CD key.

The disc version of the game needs the disc in the drive to run.

So you can wipe your XP installation then install your copy from the disc on one PC using the disc to run that, then install the steam copy on another PC.

You can actually install the disc version on as many computers as you wish but can only play on one computer at a time as you have to have the disc in the drive to actually play. I do not know whether steam allows you to do this.
