How to load a template in PHPPowerpoint

Question

I am using PHPPowerpoint which is manually installed (without composer). the lib works but not when using a template.

I tried this code:

$pptReader = PHPPowerPoint_IOFactory::createReader('PowerPoint2007');
$objPHPPowerPoint = $pptReader->load('temp.pptx');

but the browser shows:

Warning: require_once(PHPPowerPoint/Reader/PowerPoint2007.php): failed to open stream: No such file or directory in C:\xampp\htdocs\PHPPowerPoint-master\Classes\PHPPowerPoint\IOFactory.php on line 161
Fatal error: require_once(): Failed opening required 'PHPPowerPoint/Reader/PowerPoint2007.php' (include_path='C:\xampp\php\PEAR;../Classes/') in C:\xampp\htdocs\PHPPowerPoint-master\Classes\PHPPowerPoint\IOFactory.php on line 161

I also tried this:

$objPHPPowerPoint = PHPPowerPoint_IOFactory::load("temp.pptx");

And both of these as a required file and both works fine when not using a template:

require_once '../Classes/PHPPowerPoint/Autoloader.php';
PHPPowerPoint_Autoloader::register();

---

include '../Classes/PHPPowerPoint.php';

but it did not work when I tried to load a template.

I need to use a template (pptx file) for PHPPowerpoint. Please help. thanks.
