Dear LyX on Windows users,
some of you might have recently encountered problems with the PDF output
of your LyX files. documents that worked fine lead now to LaTeX errors.
These problems were introduced by a major package refactoring of the
LaTeX distribution MiKTeX that is used by default by LyX on Windows.
There are 2 ways to solve them:
1. run MiKTeX's update program _twice_
If this does not solve your problems and you still get LaTeX errors, the
easiest way is to
2. uninstall MiKTeX _completely_ and subsequently install LyX 2.2.2 over
your existing LyX installation using this new installer:
It will automatically reinstall a new MiKTeX and set up everything for
you. This might take some time depending on your Internet speed because
LyX needs a lot LaTeX packages that will be downloaded.
