Having issues finding it myself. Did you ever have any luck? I am running windows 7 Home Premium
It's, um, simply in the game folder. "worldbuilder.exe". Open your Origin games folder, open the map "Command and Conquer Generals Zero Hour", and then open the map of either specific game (Generals or Zero Hour). The worldbuilder for each is simply in those.
If you don't know how to find your game folder... open the Origin menu and select "Application Settings". In the settings screen, go to the "Installs & Saves" tab. There, under "on your computer", you can see the path of the Game library location.
To easily open the folder in your file explorer, click "Change", and in the dialog that pops up, right click the selected folder and choose "Open in new window" from the context menu. In the explorer window that opens you can then browse to the actual installation folders of your games.
