<p>The PHP exe file you specified did not run correctly [exit code 1]:
E:\xampp\php\php.exe</p>

<p>The php.ini used by your command-line PHP is: E:\xampp\php\php.ini</p>

<p>A setting in your php.ini could be causing the problem: Either the 'extension_dir' value is incorrect or the dll does not exist.</p>
