To be blunt - as usual - this is a service provided (presumably) by your hosting company and only they know how they configured it. I would recommend asking them.
Just to reiterate that we generally do not recommend these type of installers if you can possibly avoid them. By installing Moodle 'manually' (it isn't much more difficult) you then know what you did and it's a whole lot easier (possible, even) to provide you with support.
