You should give some informations about the desktop path so that Philipp can debug the code.
I will do that.
))(load luc: $TEXMFCACHE/luatex-cache/generic/fonts/otf/xits-math.luc)(load luc: $TEXMFCACHE/luatex-cache/generic/fonts/otf/xits-mathbold.luc) ! Undefined control sequence. \um_set_mathcode:nnn #1#2#3^^@-\Umathcode \int_eval:n {#1}=\mathchar@type #2\c... l.6 \setmathfont{XITS Math}That's due to the outdated lualatexiniconfig.tex I mentioned on the miktex list. Copy lualatexiniconfig.tex to some local texmf tree in a folder tex\latex\latexconfig Then add 'umath' behind 'pdftex' like this: tex.extraprimitives('etex', 'pdftex', 'umath')) Then update the fndb and rebuild the lualatex formats (probably with the user-gui of miktex, tab "formats", select lualatex and click on build).
Ah yes, that does seem to solve the problem. Danke!
