How do you install Command and Conquer Generals if you lost the key codes?

If you've lost the key codes for Command and Conquer Generals, you can try a few options. First, check if you have a digital copy tied to an account like Origin or Steam, as these may not require a physical key. Alternatively, you can look for key recovery tools or software that may help retrieve lost keys. If those options fail, consider contacting the game's customer support for assistance or purchasing a new copy.
