I have been using Lyx for some years now. Recently, I installed Lyx 2.2
along with Miktex 2.9 on a new computer (Windows 8). However, when I try to
compile a simple document I get this message (see attached). I never had
any problems with Lyx in so many years. I have tried reinstalling a fresh
version which didn't solve the problem.
The error means that pdflatex is not working on your PC. To fix this, please
1. open an Internet connection if not already)
2. open LyX and use the menu Tools->Reconfigure
3. restart LyX
did it help? if not
4. run the program "miktex update (admin)" via Windows' start menu
5. after the update was finished, run it again until no package updates
are offered6.
6. open LyX and use the menu Tools->Reconfigure
7. restart LyX
Please report back if this helped.
