Hello Arthur,
So, I copied luatex as texlua, luac and even texluac. It seems like format files was generated (i cannot bet)
Actually not; the error you get is because the format file has not been built correctly. And you probably have a problem with your configuration as well because texexec thinks he has to look in "/cont-en.fmt" for it! On Windows that doesn't even make sense, actually; but you're using Windows, right?
Right.
There is really no cont-en .lua file int he newest cont-tmf.zip.
It's a startup script for LuaTeX, built along with the formats; so it is not distributed and should be built during installation.
It is actually build, but found in My Documents...
What I miss at this point?
Format-building, mostly.
I give up. Gonna download mswincontext.zip and forget abut TeXLive. -- Best regards, Vyatcheslav Yatskovsky
