It should have installed with the game.
"Start/All Programs/EA Games/ command and Conquer Generals Zero Hour/Command and Conquer Generals Zero Hour Worldbuilder"
If its not there try reinstalling from the disk, and check again.
If its still not there, ill see what I can do to help...
Alternately, you could check in the game directory:
"Start/Computer/C:/Program Files(x86)/EA Games/Command and Conquer Generals Zero Hour/"...Worldbuilder should be at the bottom.
