I have just installed LyX version 2.2.3 on my laptop but when I wanted
to see my output in other formats, i. e., View[PDF(pdflatex)], the
pdflatex gives the following error message:
"LyX: LaTeX failed
the external program pdflatex finished with an error.
It is recommended you fix the cause of external progam's error (check
the logs)".
Your problem seems to be a major bug in MiKTeX which we are fighting the
last days.
I think we found a solution. Could you therefore please test this and
install the new LyX 2.3.0 using this installer:
http://ftp.lyx.de/LyXWinInstaller/LyX2.3.0/LyX-230-Installer-3.exe
If this works for you and you can get a PDF from the LyX UserGuide, I'll
provide a new installer for LyX 2.2.x accordingly.
thanks and regards
Uwe
