Bill,

If you have not yet uninstalled/reinstalled (or if you have and the 
problem persists), here's another thing you can try.  Open a command 
prompt (Start  Run  cmd) and navigate to your user directory (which I 
think we established was C:\Documents and Settings\you\Application 
Data\lyx16) (or lyx20 ... you can try both versions).  From that 
directory, run


C:\Program Files\whichever LyX directory\Python\python.exe C:\Program 
Files\same LyX directory\Resources\configure.py


which will do a reconfiguration of that version of LyX.  This helped 
someone else with similar symptoms.  His case was different -- he has a 
roaming profile homed on a network drive -- but it might work for you as 
well.

Re: Can't convert

Paul,

I've already uninstalled both 1.6.7 and 2.0.0.  I reinstalled 2.0 this
morning.  During the installation process, a got the error message
Downloading of MiKTeX failed.  (HTTP/1.1 4054 not found. I was
nevertheless able to continue with the installation process, and I now have
2.0.0 in Program Files.  I can open it, but when I select a file to work on
I get a message which says that the selected document class article
requires external files that are not available.  (This is what happened when
the problems started ten days ago.)  When I close this message the selected
file comes up, and I can work on it.  However, when I try to View (convert)
nothing happens.  This also happened with the previous verizion of 2.0.0
when I started having problems.  But then I would get another error message
at this point, which doesn't happen now.

I've tried reconfiguring from the Tools menu, but it doesn't help.

I'm unable to execute the stuff you suggest in the message you sent earlier
today.  StartRuncmd puts me into DOS, but I'm unable to carry out the
recommended steps.

When you uninstalled LyX, you left MiKTeX alone, right?  If so, the LyX

The configuration script does not use the registry (I just checked), so 
I think manual configuration should work.  The script tries to find 
LaTeX by running latex.exe (against a small file), so if the MiKTeX bin 
directory is on the system command path, this should succeed.  From DOS, 
you will need to execute


cd C:\Documents and Settings\you\Application Data\lyx20

check that with Windows Explorer, or running the command above will tell

mkdir C:\Documents and Settings\you\Application Data\lyx20

you need to replace you with your login id.  You may also need to put

there.  If not, from the C:\Documents and Settings\whanson prompt type

cd "Application Data"
mkdir lyx20
cd lyx20

which should get you to where you need to be (C:\Documents and
Settings\whanson\Application Data\lyx20).  Once that's your prompt, run the
Python command, slapping quotes around all paths to be safe.

Richard, Paul, LyX Users,

It's been over a week since I've been able to convert to finished text in
either LyX 1.6.7 or 2.0.0 (using DVI or View).  I've received many
suggestions, for which I am grateful, but nothing has worked.  Is there a
way to wipe both versions of LyX off my computer and start over from
scratch?  My OS is Windows XP.

Yes.  You can run the uninstallers:  go to Control Panel, look for the 
category that says install/uninstall software, click uninstall to get a 
list of software for which Windows has identified an uninstaller, and 
use that to wipe both versions.  (As an aside, there's a very nice 
freeware program for Windows called CCleaner that, among other things, 
will do the same thing, but a bit faster.  It also has a registry 
cleaner, which is useful for zapping wayward registry entries that many 
uninstallers leave behind.)  After uninstalling, look for the LyX 
program directories (under C:\Program Files) and the user directories 
(which you've previously visited) and delete anything that may have been 
left behind.

Re: Can't convert

[Paul A. Rubin]

Yes, you do have separate user directories (which is good).  The 
configuration logs in the user directories look fine.  Both of them 
found MiKTeX.  In particular, the 2.0 log shows that it has the correct 
converter path for producing PDF output, so View  PDF (pdflatex) should 
be working in 2.0.


In each version of LyX, what do you see in the Converter and Extra 
flag fields when you go to Tools  Preferences...  File Handling  
Converters and highlight LaTeX (pdflatex) - PDF (pdflatex)?  What do 
you see when you highlight LaTeX (plain) - DVI?

Re: Can't convert

Okay, this confirms that MiKTeX is correctly installed (still) and that 
it knows where the article class is located.  The error messages you 
were getting about the article class not being available suggested a 
problem with MiKTeX -- either a borked installation or something 
knocking it off the command path -- because the article class is 
*always* installed with an LaTeX distribution.


Regarding the configuration logs someone (Richard?) asked for, where did 
you find the ones you posted?  In particular, did you check in the local 
LyX folders?  (On XP those should be C:\Documents and Settings\your 
login id\Application Data\..., where ... is either lyx, lyx16, lyx2 or 
something like that -- sadly, I no longer have access to an XP box to 
nail down the exact name.)  In both LyX 1.6 and LyX 2.0, you can do Help 
 About LyX and look at the User directory entry (expanding ~ to 
C:\Documents and Settings\you\Application Data).  You might want to 
confirm that 1.6 and 2.0 point to different user directories, and that 
both directories exist.


Just out of curiosity, can you View  DVI any of the LyX help files?

Sorry this process is taking so long, but nothing obvious comes to mind, 
and your symptoms seem to have changed a bit along the way.  A working 
installation suddenly breaking sometimes happens when something 
unrelated to LyX screws with MiKTeX, but that does not seem to have 
happened to you.

Re: Can't convert

[Paul Rubin]

Okay, this confirms that MiKTeX is correctly installed (still) and that 
it knows where the article class is located.  The error messages you 
were getting about the article class not being available suggested a 
problem with MiKTeX -- either a borked installation or something 
knocking it off the command path -- because the article class is 
*always* installed with an LaTeX distribution.


Regarding the configuration logs someone (Richard?) asked for, where did 
you find the ones you posted?  In particular, did you check in the local 
LyX folders?  (On XP those should be C:\Documents and Settings\login id>\Application Data\..., where ... is either lyx, lyx16, lyx2 or 
something like that -- sadly, I no longer have access to an XP box to 
nail down the exact name.)  In both LyX 1.6 and LyX 2.0, you can do Help 
> About LyX and look at the "User directory" entry (expanding ~ to 
C:\Documents and Settings\\Application Data).  You might want to 
confirm that 1.6 and 2.0 point to different user directories, and that 
both directories exist.


Just out of curiosity, can you View > DVI any of the LyX help files?

Sorry this process is taking so long, but nothing obvious comes to mind, 
and your symptoms seem to have changed a bit along the way.  A working 
installation suddenly breaking sometimes happens when something 
unrelated to LyX screws with MiKTeX, but that does not seem to have 
happened to you.

Just as an FYI, the Desktop path _does_ contain spaces if it is translated into
an absolute path (it maps to C:\Documents and Settings\you\Desktop).

Is it possible that your MiKTeX installation (I assume you are using MiKTeX)
became borked during an upgrade?  If you open a command prompt and run
'kpsewhich article.cls', do you get a path to the article class file?

The problem now seems to be that LyX hasn't found your LaTeX
installation. Can you please run Tools>Reconfigure, and then post the
configure.log file that will be dumped in your user directory? (See
Help>About LyX for where it is located.) Or did we already do that? I
can't remember.

Anyway, that is certainly the first problem.

Windows XP Users,

The attached message string details my story.  Basic Summary:

My OS is Windows XP, and I've been using LyX 1.6.7 without problems for
about a year.  Starting a couple of days ago I've been unable to update or
view the DVI versions of my files.  Clicking the dvi or PS icons brings an
error message: Cannot convert file  An error occurred whilst running
phython -tt.

I downloaded LyX 2.0.0, and I can open my documents using it.  But, when I
do, I get a message saying that I need the document class article, and I'm
directed to 3.1.2.2 of the User Guide.  Unfortunately I don't understand the
information given there on how to install the appropriate package files.

After I get into one of my documents (using 2.0.0) and I click View (which I
assume is asking for the compiled version that the dvi button yielded in LyX
1.6.7), I get a file name error message:  The directory path to the
document cannot contain spaces.

The suggestions offered by Richard Heck and Julien Rioux, while much
appreciated, have not helped.

Just one possible explanation of the failure:

The python scripts shipped with LyX are not tested with all possible 
python version, but they should work with the python installation 
shipped with LyX. LyX installs its own python in a subfolder of Program 
Files/LyX. If you have installed python separately, or another program 
has installed python, this might conflict with LyX.

Re: Can't convert

I'm not aware of any installation of python.  I have an LyX16 folder with a
Python subfolder and an LyX 20 folder also with a python subfolder.  The
former contains python26.dll and python.exe.  The latter contains python
27.dll, python.exe, and pythonw.exe.

The original error message, which referred to python -tt occurred while I
was running LyX 1.6.7.  When I switched to LyX 2.0.0 none of the error
messages referred to python, but I still couldn't convert.  Details in the

Just one possible explanation of the failure:

The python scripts shipped with LyX are not tested with all possible 
python version, but they should work with the python installation 
shipped with LyX. LyX installs its own python in a subfolder of Program 
Files/LyX. If you have installed python separately, or another program 
has installed python, this might conflict with LyX.

Re: Can't convert

[William Hanson]

I'm not aware of any installation of python.  I have an LyX16 folder with a
Python subfolder and an LyX 20 folder also with a python subfolder.  The
former contains python26.dll and python.exe.  The latter contains python
27.dll, python.exe, and pythonw.exe.

The original error message, which referred to "python -tt" occurred while I
was running LyX 1.6.7.  When I switched to LyX 2.0.0 none of the error
messages referred to python, but I still couldn't convert.  Details in the
string of messages between me and Richard Heck.

Works fine for me here.  Keep in mind that there are at least three PDF 
file formats defined within LyX, because different compilation methods 
(ps2pdf, pdflatex, dvipdfm) have different requirements.  On my box 
those are designated pdf, pdf2 and pdf3 respectively, and I'm pretty 
sure that's standard across installations.  If you create a converter 
from DOT to pdf3, say, and then use View - PDF (pdflatex) to see the 
output (which is creating pdf2 output), presumably something will break.


I always use pdflatex, so I created a Dot file format and then a Dot to 
PDF (pdflatex) converter.  The latter used the command line 'dot -Tpdf 
$$i -o $$o'.  I have the dot executable on my system command path; 
otherwise, I would need either to specify a full path in the converter 
or add the path to the LyX path prefix.


Hello Paul,

Maybe you could contribute this converter to LyX? I am very interested 
in dot but never took the time to try to integrate it within LyX.

I tried this many times but no success. I am aware of the pdflatex (etc)
issue. It is not called 'pdf3' on my system, it is called 'PDF
(pdflatex)'. That is the standard on Fedora and Ubuntu systems, if not
elsewhere, so I don't think you're right about 'pdf3' etc.

This converter system is way too delicate IMHO: if you get it wrong, you
get minimal and rather cryptic error messages. It's also impossible for
someone to help to diagnose a problem, because you can't just sent me
your config file (AFAIK) and you can't tell what stuff is different on
my system compared to your system.

FWIW, I think that rather than an all-powerful GUI for editing
converters, file formats, etc, these things should be stored in flat
platform-specific configuration files that can be packaged for
distribution as 'plugins' eg a set of LyX configuration files + linux
package dependences = support for Graphviz in LyX. This would take the
voodoo out of the job of getting LyX working with various different file
formats, and allow end-users to make use of *the tools they know
already* in order to get extra features working with LyX. I say this,
but I'm not going to come and help, so you best ignore me here :-)

Should be both:  in Tools - Preferences - File formats, if I highlight 
'PDF (pdflatex)', that's the entry in the 'GUI name', while the entry in 
'Format' is pdf2.  FWIW, if you want to do a file export from the

Shouldn't have anything to do with the converter working or not, though, 
so long as the converter entry points to the right output GUI name.

I tend to agree here, to the extent that if LyX gets an error message 
from an external command, it should forward it to the user.  I don't 
think that's always the case, though.  I suspect that sometimes LyX runs 
an external process and the child process exits with a nonzero error 
code but not much else.  LyX can't tell you what it doesn't know (i.e., 
LyX is not an academic).



It's also impossible for
someone to help to diagnose a problem, because you can't just sent me

Actually, you can send a piece of an appropriate config file.  In your 
LyX home directory, there's a file named 'preferences'.  It should 
contain a line defining the DOT file type and additional lines for each 
related converter you added.  Mine read as follows:


\format dot dot Dot  auto auto vector
\converter dot pdf2 dot -Tpdf $$i -o $$o 

Note that this is exactly what I entered in the all-powerful GUI.  :-)

Well, it would not be hard for someone to provide a patch file that one 
could apply to the preferences file.  The user would have to know how to 
merge in a patch file (or else LyX would have to provide a patch merge 
utility).  Unfortunately, these things are not entirely 
one-size-fits-all, even within operating systems.  For instance, my 
converter above works because I have the dot executable on my system 
command path.  Otherwise I need to provide the path to it someplace -- 
which means your plug-in installer needs to detect the location of dot 
on my system, or else open up a dialog and ask me to locate it.


If the converter entries above don't work on your system, it's possible 
that either LyX (more precisely, the child shell it spawns) can't find 
the dot executable or else lacks permission to run it.  Try the 
following.  Open a LyX doc with a dot image embedded and try View - PDF 
(pdflatex), which I gather will fail silently.  With LyX still running, 
open a terminal and navigate to the LyX temporary directory.  Verify 
that a copy of the DOT file sits there, probably with the name mangled 
by LyX.  Assuming so, run the converter from the terminal, using exactly 
the syntax of your converter entry (but substituting the mangled file 
name for $$i and the same name with a pdf extension for $$o).  In my 
case that means 'dot -Tpdf mangled name.dot -o mangled name.pdf'. 
If it fails, maybe you'll get a helpful error message in the terminal 
window.

Happy to oblige, but I'm not sure what there is to contribute.  These

Preferences...):


\format dot dot Dot  auto auto vector
\converter dot pdf2 dot -Tpdf $$i -o $$o 

If somebody wants to build that into a future release (which I assume

I think that that is the wrong approach. It is the job of the person
writing the plugin to specify the correct location for 'dot' or whatever
else. LyX should not take on the job of going out and finding all the
necessary tools.=

The usual solution for this problem is to provide a '#include' type
functionality for configuration files. For example, in the case of
Apache on Fedora you have /etc/httpd/conf/httpd.conf which contains:

 #
 # Load config files from the config directory /etc/httpd/conf/conf.d.
 #
 Include conf.d/*.conf
This mechanism allows external packages to drop files in the
/etc/httpd/conf.d directory as required, to add new behaviour to Apache.
This means that package managers are not required to *patch* files
already installed in the system, which is always a bad idea (how to
safely un-patch the file if it has been modified since originally being
patched?)
http://httpd.apache.org/docs/1.3/mod/core.html#include

Another approach is that of Gedit, which has a little file format
*.gedit-plugin. Any files having this extension contained in
/usr/lib/gedit-2/plugins/, or in ~/.gnome2/gedit/plugins/ are loaded and
run when gedit starts, allowing the loaded code to add functionality of
Gedit via a particular plugin API.
