Where is php.ini file located in phprunner v11?

I will like to change the timezone setting in php.ini file and in phprunner 10.9 it is located C:\Program Files\PHPRunner 10.9\EmbeddedServer\php\php.ini. But in phprunner v11, I can't seem to find phprunner 11 folder inside Program Files folder. I have both v10.9 and v11 installed in my computer but only v10.9 folder can be found in Program FIles or Program Files(86) or Program Data. Where is phprunner 11 folder?
