Sometimes the World Builder to C&C 3 does not install because there is no backslash in the registry path of C&C 3. This is mainly caused only when steam installs the game. Try to do this and see if it solves your problem:
1. Hold the Windows logo key and hit R. (⊞ Win+R)
2. type in the command box regedit
3. Go to HKEY_LOCAL_MACHINE > SOFTWARE > (Wow6432Node > )Electronic Arts > Electronic Arts > Command and Conquer 3 Kane's Wrath (or Tiberium wars, whichever one you are installing the World Builder for; it works for both.)
4. Double Click on the InstallPath to and add a
\ to the end of it. Hit OK and exit all windows.
Now it should read:
"c:\program files (x86)\steam\steamapps\common\command and conquer 3 tiberium wars\"
Instead of:
"c:\program files (x86)\steam\steamapps\common\command and conquer 3 tiberium wars
5. Try installing the World Builder again.
Hope that fixes it for you!
