Openoffice settings in Previews

After installing openoffice according to the documentation, the DOC file does not generate a preview image.

Is this set correctly in the Config.php file?

I found an error in ‘preview_libreoffice_path’ that has been changed to ‘/usr/bin/openoffice4’. But still can’t preview.
