One can use the binaries from w32tex.org, but they won't be able to use the miktex tools (on-the-fly installation etc), and you need also a texmf.cnf, ddl for kpsewhich etc. Imho it would be easier to install a texlive in parallel and exchange the binary there. Switching between miktex and texlive is easy: you only need to change the path variable. -- Ulrike Fischer http://www.troubleshooting-tex.de/
