Thread:Project:Support desk/Problem opening WebStart.php

Hi, I'm completely new to MediaWiki, and I'm currently trying to set up an offline wiki on my computer using this manual: https://www.mediawiki.org/wiki/Manual:Installation_on_Uniform_Server_%28Windows%29#Configure_the_wiki

At "Configuring the Wiki" variables, I have to click the link "http://localhost/wi/mw-config/index.php" (I renamed the MediaWiki folder to "wi" as required in the instructions).

However, I get an error message as follows:

Warning: require(./includes/WebStart.php) [function.require]: failed to open stream: No such file or directory in W:\www\wi\mw-config\index.php on line 29

Fatal error: require [function.require]: Failed opening required './includes/WebStart.php' (include_path='.;/usr/local/PHP/includes;/usr/local/PHP/pear;/home/admin/www/plugins/pear/PEAR') in W:\www\wi\mw-config\index.php on line 29

Any idea what I got wrong? I'm quite sure I followed the instructions closely.
