Re: [NTG-context] Running Mark IV / luatex: unknown script: context

Thank you but that doesn't really help, the errors are just the same. I suppose both values for TEXMFCNF works.

In principle, it should really be the name of the directory containing texmf.cnf, not the path to the file itself. But in any case, you have to run "luatools --generate" after that. And then, "luatools cont-en.tex" should return the location of the file. Does it? If it does, you should probably be able to proceed. Arthur
