When working on a university project we use Texmaker as our editor. We share our documents and compile our master in a dropbox folder. Now when I try to quickbuild the master document I get this message:


The log file looks like this:

2016-02-26 10:58:32,049+0100 FATAL pdflatex - Invalid argument: path="*.aux"

2016-02-26 10:58:32,049+0100 FATAL pdflatex - Info: path="*.aux"

2016-02-26 10:58:32,049+0100 FATAL pdflatex - Source: Libraries\MiKTeX\Core\File\win\winFile.cpp

2016-02-26 10:58:32,049+0100 FATAL pdflatex - Line: 418

The only thing that have changed since last semester, is the different folders. I have Texmaker 4.5 and MiKTeX 2.9

Edit: I can still build the old project from Google drive, but I can't build the new project from dropbox.

    Just to rule out texmaker, can you compile the rapport from the command line? – daleif Feb 26 '16 at 11:13
  • I'm not sure how to do that? From the command prompt? And then the directory C:\Users\Andreas Nouoruzi\Dropbox\P2\Rapport ? And what then? And thanks for the reply – Andreas Grøndahl Nourouzi Feb 26 '16 at 11:38
  • pdflatex Rapport.tex – daleif Feb 26 '16 at 11:39
  • I'm not used to using commandopromt. When i start, it says C:\users\Andreas Nourouzi> Should i then write: C:\Users\Andreas Nouoruzi>\Dropbox\P2\Rapport pdflatex Rapport.tex or C:\Users\Andreas Nouoruzi>C:\Users\Andreas Nouoruzi\Dropbox\P2\Rapport pdflatex Rapport.tex? – Andreas Grøndahl Nourouzi Feb 26 '16 at 11:54

I got almost this error (slightly different):

INFO  pdflatex - starting with command line: "C:\Program Files\MiKTeX 2.9\miktex\bin\x64\PDFLaTeX" --max-print-line=16384 --synctex=0 --c-style-errors --interaction=nonstopmode MyFile.tex
FATAL pdflatex - Invalid argument: path="MyFile.pdf"
FATAL pdflatex - Info: path="MyFile.pdf"
FATAL pdflatex - Source: Libraries\MiKTeX\Core\File\win\winFile.cpp
FATAL pdflatex - Line: 493

For me the cause of this error was another program having the PDF file open.

Closing the program fixed the issue.
