Re: [NTG-context] installing MKIV

luac5.1.exe [TO] luac.exe etc.

Alternatively, you can use LuaTeX itself as the lua interpreter and compiler. That is, the same binary will act as: LuaTeX proper when called luatex(.exe) lua when called texlua(.exe) (equivalent to luatex --luaonly) luac, the compiler, when called texluac.(exe) So you don't even need lua anymore.
