Using a customised configuration according to [1] will not work on some Windows systems. I think because of issues with blanks in the standard file pathes of Windows 2003 - "Program Files" and "Program Files (x86)" where gs, IM and xpdf install by default.
For Example with the following configuration PDFHandler will not work. There is no reaction of the Extension like mentioned in [2].
<pre>
Konfiguration von pdfhandler
$wgPdfProcessor = 'C:\Program Files\gs\gs9.07\bin\gswin64.exe';
$wgPdfPostProcessor = $wgImageMagickConvertCommand; if defined via ImageMagick
$wgPdfPostProcessor = 'C:\Program Files (x86)\ImageMagick-6.6.9-Q16\convert.exe'; // if not defined via ImageMagick
$wgPdfInfo = 'C:\Program Files\xpdf\bin64\pdfinfo.exe';
$wgPdftoText = 'C:\Program Files\xpdf\bin64\pdftotext.exe';
</pre>
When running /maintenance/runjobs.php the following error comes up always:
<pre>
Der Befehl "C:\Program" ist entweder falsch geschrieben oder konnte nicht gefunden werden.
