- Conclusion: I cannot do more right now to wait until MiKTeX releases
the fixes for the 2 bugs.
Here is the solution in form of a new installer:
http://ftp.lyx.de/LyXWinInstaller/LyX2.3.0/
I don't want to write pages to describe the problematic in detail.
Summarized, the problem is that MiKTeX uses a new package handling
system and in order to use LyX with MiKTeX this new system must be used.
Therefore existing MiKTeX installations must be updated. Unfortunately
the normal update mechanism fails due to a bug in the MiKTeX installer
that was released in October last year and the MiKTeX maintainer cannot
fix this. Affected by this bug are most users who installed or updated
MiKTeX between October and January.
The only solution is to force 2 graphical update runs on MiKTeX where
the users just have to click in summary 4 times "Next". Not nice but
there is definitely no other way.
I expect some users not to click on Next but maybe on Cancel or Close.
Those will get in some cases as result a unusable MiKTeX installation.
Therefore we need this text in the release notes and the announcement mail:
"
If you cannot get a PDF from a LyX file after installing LyX 2.3.0 under
Windows and the error message you get is that "paths must not contain
spaces" or similar, you must do the following:
1. uninstall LyX 2.3.0
2. uninstall MiKTeX
3. reinstall LyX 2.3.0 using the bundle installer
"
As soon there is a new MiKTeX installer available I will release another
installer because this will fix 2 minor bugs (for example that on some
installations the MiKTeX package manager pops up unexpectedly).
