Hi Paul,

thanks for your help! Yes, there is cygwin install on the computer. I now
looked for the cygwin directory in system path variable, but there was only
the miktex path, so I'm not sure if that is the problem or if I looked at
the wrong variable. This is what's in the path variable:

C:\Windows\system32
C:\Windows
C:\Windows\System32\Wbem
C:\Windows\System32\WindowsPowerShell\v1.0\
C:\Program Files (x86)\MiKTeX 2.9\miktex\bin\
C:\Program Files\OpenAFS\Common

C:\Program Files (x86)\OpenAFS\Common
C:\Program Files (x86)\OpenAFS\Client\Program
C:\Program Files (x86)\Heimdal\bin\
C:\Program Files\Heimdal\bin\

and these are the paths from LyX:

$LyXDir\bin;
$LyXDir\Python;
$LyXDir\Python\Lib;
$LyXDir\Perl\bin;
$LyXDir\imagemagick;
C:\Program Files (x86)\MiKTeX 2.9\miktex\tex\latex;

Hi Paul and everyone!

I found the solution to my problem on the LyX troubleshoot wiki. I had a
problem with an UNC path. Here is a copy of the solution:

LyX does not start and gives the error message: unable to find textclass file

This problem may come into existence if you use LyX on a windows-pc where
your windows/application profile is not stored local but on an UNC path
(i.e. \\Username\Applications\LyX). One solution I have found is the following:

Uninstall LyX from your PC if you have used an installation folder whose
name exists of seperate words like C:\Program Files.
Reinstall LyX and consider, that you use a folder whose name exists of
just one word like C:\Lyx15
Start the Command Prompt in windows (Start - All Programs -
Accessories - Command Prompt)
Change directory to C:\ (type c:)
Type c:/lyx15/python/python.exe c:/lyx15/resources/configure.py in the
Command Prompt and press return
After the configuration has been finished you will find 4 files in the
directory c:\ - configure.log, lyxrc.defaults, textclass.lst and packages.lst
Cut these 4 files and paste them into the \\Username\Application
Data\LyX folder. If a directory for Lyx does not exist create a new one.
Start Lyx 

The problem can arise even if you do not use a UNC path for the windows
profile. In this case steps 5-8 are sufficient and can be carried out using
the default Program Files location.

Sorry for troubling you and again thanks for your help!

Cheers,
Fabian
