Dear Wolfgang and Aditya, I downloaded http://www.pragma-ade.com/context/install/mswincontext.zip. It is a 2007-08-08 15:12 version, I use this on Windows XP Professional Hungarian Edition SP2. I have run command texexec --dvips próba.tex. Here is the error message: c:\Program Files\ConTeXt\isoimage\usr\local\context\tex\texmf-mswin\bin>texexec --dvips próba.tex TeXExec | processing document 'próba.tex' TeXExec | no ctx file found TeXExec | tex processing method: context TeXExec | TeX run 1 TeXExec | writing option file próba.top TeXExec | using randomseed 17 TeXExec | tex engine: pdftex TeXExec | tex format: cont-en pdftex: unrecognized option `-alias=context' pdftex: unrecognized option `--undump=cont-en' pdftex: unrecognized option `-tcx=natural.tcx' This is pdfTeX, Version 3.141592-1.40.4 (Web2C 7.5.6) \write18 enabled. kpathsea: Running mktexfmt pdftex.fmt I can't find the format file `pdftex.fmt'!
