So my question: is there an old version ProTeXt
(namely the one based on MiKTeX 2.6) available somewhere?
All old versions of protext (among other things) are archived at
ftp://tug.org/historic/systems/protext. (Whether there was one based on
miktex 2.6, I don't know.)
I've added a link to tug.org/protext for this.
Thanks,
Karl
