As it says on the JavaCC download page,

    The downloaded file is a self-extracting Java executable. Run it
    like any other Java program to install JavaCC.

In other words, put it in a directory and run

    java -cp . JavaCC2_0

(if the file is named JavaCC2_0.class). This starts up the GUI
installer program. (Maybe one of these days DemeterJ will have one of
its own...)

You'll need to edit demjava.bat to replace "c:\demjava" with your
installdir. I meant to fix it so that it used the value of
DEMJAVA_HOME but I still don't know enough about DOS batch file
syntax. If anyone knows how to do this (namely, set an environment
variable to a value if it has not already been set) please drop me a line...
An alternative is to install cygwin and use the demjava shell script.
Or install linux...
