First question: are these machines self-contained, or do users have 
their home directories on a remote server?  (There have been two reports 
of this problem recently from people using remote servers.)


Assuming that your home directories are stored on the machines, you 
might try opening a DOS shell and changing to the Resources folder under 
the LyX installation directory.  There is a script 'configure.py' there. 
 Try running it.  (If you don't have the full Python installed and 
associated with .py file types, you will need to run 'python 
configure.py' or possibly '\python configure.py', where  is 
the path to the copy of Python installed by LyX.


In the event that doesn't work (it usually does), you should at least 
get some informative error messages in the DOS window.

Nothing special. Actually I installed it a first time with the default

Seeing in the list that some people had problem with the space in the 
pathname, i reinstalled it in c:/appli. Same problem.

The problem is

This is all very strange. I copied the file again, and it now seems to be
working.

Sorry for the false alarm, and thanks for the advice.

That means you probably dont have Msys in your Windows PATH

Suppose that you have Msys etc installed in C:\Msys\1.0\bin
and bin is where sh.exe is located. Then you should try from

C:\Msys\1.0\bin\sh.exe configure  [using the dos cmd prompt]

you would be in your ~lyx\resources\lyx directory which contains
the configure file, and type in "C:\Msys\1.0\bin\sh.exe configure" 
(but no quotes when you type it) from the lyx\resources\lyx directory.

For "me" this looks like:
C:\Lyx\resources\lyx> C:\msys\1.0\bin\sh.exe configure 

But you want to substitute your actual installation location,
maybe c:\program files\lyx\resources\lyx, in place of "my" location.

That's a bit curious.  I take it that you still got the "unable to find 
layout description/check textclass.lst" message after you copied the 
global textclass.lst file over the broken local one?


Other than comments, the contents of the textclass.lst file is a list of 
LaTeX document classes, each line culminating with true or false 
according to whether a layout was found.  Is anybody in the (global) 
list flagged true?  In particular, you should have the following line:


"article" "article" "article" "true"

which signals that the basic article class has a layout.  If nobody is 
flagged true (don't know if that's even possible), it might signal a 
fundamental problem with MiKTeX.


Speaking of MiKTeX, have you verified that it's working post-update?


When I try running sh configure, it doesn't run because paths don't appear
to be set up right. I decided not to try to fix that because I wasn't sure
it would get me anywhere.


LyX 1.3.6 contains a "path prefix" that it prepends to your system path. 
 The path prefix contains (should contain?) the path to the MinSYS bin 
directory, where sh and related programs live.  So you don't need that 
on your system path for LyX to work.


In any case, the main purpose of running the configure script would be 
to generate the global textclass.lst file, which you already have.  The 
secondary purpose would be to verify that latex works (and that LyX can 
find it).


So the immediate mystery is why LyX won't settle for the global 
textclass.lst file.  Best guess from here would be that something is 
amiss with the file (corrupted, or doesn't show any usable layouts).

The empty textclass.lst phenomenon occurs repeatedly in the list, but

Were the "skipped" packages LaTeX packages (and, if so, are you using
MiKTeX), or were they supporting programs (Ghostscript, MinSYS, ...)?

There are (or should be) two copies of textclass.lst on your system.
One would be in C:\Program Files\LyX\Resources\lyx (assuming that's
where you installed LyX), and the other would be in C:\Documents and
Settings\your_id_here\Application Data\lyx.  Which did you look at
(both?), and did you see content in them, or were they empty (zero
bytes)?  The most common, if not only, problem with textclass.lst on
Windows systems seems to be the configure script writing a zero-length
file as a result of something going wrong.

By "manually run", do you mean running 'sh configure' in the C:\Program
Files\LyX\Resources\lyx directory?  If so, does that spew a lot of
progress information to the shell window and, most importantly, does it
indicate that a working copy of latex.exe was found?
