Sorry, that isn't accurate. For record, I correct it. The colon ":" for path delimiter would be valid for cygwin TeX Live commands, provided that the path name containing drive letter specifier such as "c:" and path separator "\" are turned into suitable forms for cygwin commands. Thus > 1. Customize `TeX-kpathsea-path-delimiter' to ";". this option alone wouldn't work because cygwin TeX Live commands would still see .;c:/Users/bruno/AppData/Roaming/.emacs.d/elpa/auctex-13.1.1/latex; as TEXINPUTS value, which they won't understand correctly.

(Or deinstall cygwin itself.) is needed. Regards, Ikumi Keita #StandWithUkraine #StopWarInUkraine
