it should not...
but then again, I've never uninstalled SWoWWII or Battlecraft
If it is a matter of disc space for SWoWWII and he's afraid of messing up what is already working fine, then just have him delete the Xpack2 subdirectory in c:\program files\ea games\battlefield 1942\mods and that should do it.
