Thread:Project:Support desk/Mediawiki is not installing

I am trying to install media wiki. I downloaded the software, extracted and place it in my local server, so my url is http://127.0.0.1/wiki (I am using wamp).

When opening this path I got a page saying setup wiki first. When I click to install, it shows the page is not available and the url is http://127.0.0.1/wiki/mw-config/index.php

I am using mediawiki 1.19
