Hello, Curiouser and curiouser :) I've deleted @echo off from mtxrun.cmd, and what it shows: I:\context\tex\texmf-mswin\bin>mtxrun.cmd --script cache I:\context\tex\texmf-mswin\bin>setlocal I:\context\tex\texmf-mswin\bin>set ownpath=I:\context\tex\texmf-mswin\bin\ I:\context\tex\texmf-mswin\bin>texlua "I:\context\tex\texmf-mswin\bin\mtxrun.lua " --script cache Error in lua file loading: cannot open : No such file or directory I:\context\tex\texmf-mswin\bin>endlocal The texlua complains has completely no sense, since mtxrun.lua file DOES exist at that location. Or what is it looking for? -- Best Vyatcheslav mailto:yatskovsky@gmail.com
