Perhaps you tried to install it in the same location as one of the other versions. The linux version's installation script gives you a --prefix option for its location, and I expect the .exe gives you the same functionality in some manner. If you create a symlink somewhere in your PATH that points to the favoured version, "lilypond" will run that version; other can be run by giving (clicking on) an appropriate specific path to the executable.
