Thanks, Ian 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. /Paul

Did you do something special, besides installing in a non-standard directory? Nothing special. Actually I installed it a first time with the default dir (c:/Program Files/Lyx14) but it was failing. 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 Unable to determine the system directory having searched C:/appli/LyX14/bin/C:/appli/LyX14/Resources/ LyX should have searched in C:/appli/LyX14/Resources/ instead. Yes. Note that this message is confusing: - did it search separately c:/appli/lyx14/bin, and c:/appli/lyx14/resources (in which case it should have found the correct dir), and did the error printing by concatenating the 2 dirs? - or did it search a single dir of the form c:/appli/lyx14/bin/c:/appli/lyx14/resources/ ??

I had only looked at the textclass.lst file in the C:\Program Files\LyX\Resources\lyx directory. You are correct that the one that I did not check (in C:\Documents and Settings\your_id_here\Application Data\lyx) is 0-length. I copied the global one to the local one but that didn't work. 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). Paul
