Dear gang, In the past I updated to the latest via installing cont-tmf.zip (and luatex.exe if needed) manually, but recently I switched to first-setup.bat. I got things working on one 64-bit machine (vista), and want to set up context on another (windows7), also 64-bit. Normally all I need to to do is zip/rar the tree, move it to the second machine, and voila, I'm up and running. This time, however, it doesn't work; when I run a file I get ===================== This is LuaTeX, Version 0.97.0 (TeX Live 2016/W32TeX) system commands enabled. . <*> cont-yes.mkiv ? ===================== as well as a complaint from windows7: ===================== Assertion failed! Program: C:\<path>\luatex.exe File: variable.c line: 36 Expression: kpse -> program_name ===================== What do these two complaints each mean? After this, I tried running first-setup.bat again on the windows7 machine, got the following errors: ===================== mtx-context | running command: pdftex --ini --etex --8bit cont-en.mkii \dump warning: c:/ConTeXt/tex/texmf/web2c/texmf.cnf:49: (kpathsea) No cnf value on lin e: OSFONTDIR =.

I can't find file `cont-en.mkii'. <*> cont-en.mkii \dump (Press Enter to retry, or Control-Z to exit) Please type another input file name: [:] mtx-context | running command: pdftex --ini --etex --8bit cont-nl.mkii \dump warning: c:/ConTeXt/tex/texmf/web2c/texmf.cnf:49: (kpathsea) No cnf value on lin e: OSFONTDIR =.

I can't find file `cont-nl.mkii'. <*> cont-nl.mkii \dump (Press Enter to retry, or Control-Z to exit) Please type another input file name: ===================== Since I don't use mkii I ignored these errors and moved on, although both files are there in the tree - and I do not get this error on the original/vista machine. In any case, when I now run a file I get the same two luatex errors as at the beginning of this message. What's going on here? How do I fix it?
