A-ha! The solution that file name should be wingding.ttf versus wingdings.ttf. OSFONTDIR is ok, my installer sets it properly :) Thanks for help. works perfectly. I only cannot understand what the following do: \def\Check% {{\tfa\symbol[box]}}

Apparently the font is not found. So make sure that TeX can find the font. Probably you need to check whether the OSFONTDIR is set correctly. Otherwise copy the to a place e.g. texmf-local en run luatools --generate.

I hop this helps.
