How to Change the Serial of "Red Alert 2"by Amanda RumbleUpdated September 28, 2017
Red Alert 2, like almost all other PC games, requires a serial to install. The serial key gets stored in the registry of the computer. The game frequently refers to this information to verify your identity and the validity of the install. It may become necessary to change this number if you get a different copy of the game or give an older one to a friend, for example. The process is quick and rather simple.
Click "Start" and select the "Run" button.
Type "Regedit" into the box that appears and press "Enter" or click "OK."
Navigate to "HKEY_CURRENT_USER" under the "Computer" heading.
Select "Software" and scroll down the list until you find either "Electronic Arts" or "EA Games."
Search for "Command and Conquer Red Alert 2 Yuri's Revenge." Click the left arrow and scroll down to "ERGC."
Look in the right hand portion of the screen for the CD-KEY.
Double-click on the CD-KEY and enter your new key in the box labeled "Value Data." Your key is now changed in the system and you are able to play.
Back up the registry before you make any modifications. This ensures that any damages can be repaired, especially if the game doesn't work. Go to "File" and click "Export." Save the backup copy to a location you can easily identify.
