An uncaught Exception was encountered Type: RuntimeException

I am encountering the above error after executing this statement:

//$temp_file is the .docx file created by phpWord
//res is the name of the .docx file without the extension
Gears\Pdf::convert('C:\xampp\htdocs\yu\\'.$temp_filename, 'C:\xampp\htdocs\yu\\'.$res.'.pdf',
                [
                    'converter' => function()
                    {
                        return new Gears\Pdf\Docx\Converter\LibreOffice
                        ([
                            'binary' => 'C:\Program Files (x86)\LibreOffice 5\program\soffice.exe',
                            'output'=>'C:\xampp\htdocs\yu'                            
                        ]);
                    }
                ]);

My backtrace is as follows:
