Hello,
Please run the included example, advances/Transformphp, using the CLI mode; this is:
$ php Transform.php
Note that there are four options to do the transformation; please try all of them and enable the debug mode (http://www.phpdocx.com/api-documentation/advanced-conversion-plugin/convert-Word-docx-into-pdf-with-PHP). And check your server logs to find any error or something missing.
Regards.
