Hello,

I'm using Nuxeo 7.2. on Windows Server 2008 R2. When I try to preview a pdf file I get the following message:

Technical issue: Blob path: default org.nuxeo.ecm.platform.preview.api.PreviewException: Error while converting via CommandLineService

(Full stack trace follows)

PDF generation works and thumbnails of pdf in advanced search also works.

If I examine the command that is failing:

cmd /C pdftohtml -c -enc UTF-8 -noframes “C:\ProgramData\Nuxeo\tmp\nxblob-7304333945179266011.pdf” “C:\ProgramData\Nuxeo\tmp\pdf2html_1430317720612”\index.html

I can see that the folder “C:\ProgramData\Nuxeo\tmp\pdf2html_1430317720612” is created but the temporary pdf file (“C:\ProgramData\Nuxeo\tmp\nxblob-7304333945179266011.pdf”) does not exist.

pdf2html got installed by the Windows Installer and seems to work since I can generate pdf from office documents but it's not in my system path: if I write pdf2html in a standard command line it does not get found.

Here is the stack trace of the error:
