Hi,
My system is unix and my platform is linux-64. I installed ConTeXt LMTX as
described, namely in my home and in the directory /data /context/
I then tried to compile but without success a file :

[viserion@archlinux ~]$
/home/viserion/data/context/tex/texmf-linux-64/bin/context area.tex
mtx-context     | run 1: luametatex
--fmt="/home/viserion/data/context/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/formats/luametatex/cont-en"
--jobname="area"
--lua="/home/viserion/data/context/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/formats/luametatex/cont-en.lui"
--c:currentrun=1 --c:fulljobname="./area.tex" --c:input="./area.tex"
--c:kindofrun=1 --c:maxnofruns=9
--c:texmfbinpath="/home/viserion/data/context/tex/texmf-linux-64/bin"
"cont-yes.mkiv"

sh: luametatex : commande introuvable
mtx-context     | fatal error: return code: 32512
[viserion@archlinux ~]$
Thanks
