Elgg installation problems using XAMPP

Hello there,

I'm new to Elgg, and what i wanted to do was install it on my computer
using XAMPP so i could have a little play around with the site. Now i
followed one guide from a Google Elgg forum however, i couldnt get it working (http://groups.google.com/group/elgg-users/browse_thread/thread/e6322c5933216cdf),
so i headed over to Elgg's Offical Site and did this tutorial,
http://docs.elgg.org/wiki/Install_XAMPP. Now, when installing Elgg,
you can either choose to do it manually, or via that web page, ive
tried both still nothing, however, when i do use that webpage, it
doesnt seem to rename that setting.example.php file. The error i get
is this:

Server error!
The server encountered an internal error and was unable to complete
your request. Either the server is overloaded or there was an error in
a CGI script.

If you think this is a server error, please contact the webmaster.

I have no idea what this means, so please help!!!
