It is really easy. Just go to the elyxer directory (where setup.py
resides) and do:

I don't know the exact location of site-packages on Windows, but I am
sure that updating Python will not affect it. (Updates from 2.5 to 2.6
will change the location of the directory, but that is a big change
that happens seldom and scripts may have to be updated. Also, this
update requires certain Python knowledge.)

I think in this case you might: first install Python, then install
eLyXer as a module.
