Dear Jaroslav,

I tested path settings, but it seems it is OK (c:\windows\system32 is in my PATH)

Sorry for my mistake. Very difficult problem!! % latex.tex \documentclass{article} \begin{document} \immediate\write18{echo "OOOOOOOOOOOOOOOOOOOOOOOO"} \end{document} should print ... ... No file latex.aux. "OOOOOOOOOOOOOOOOOOOOOOOO" (./latex.aux) ) No pages of output. Transcript written on latex.log. for pdflatex --shell-escape latex Best, Akira
