Could you post PATH? > LyX outputs: > > Looking for python v2.x or 3.x ... > Examining C:/Program Files/MiKTeX 2.9/miktex/bin/x64//pythontex.exe > Warning: No python v2.x or 3.x binary found. What is this "pythontex.exe" ??? Some googling gives https://github.com/gpoore/pythontex/issues/123 So, maybe you don't have python installed at this place. (I think, python != pythontex, because pythontex needs to find python) > Doesn't that indicate that LyX is looking at the wrong place and then > maybe gives up too early?
