Problem XAMPP Win32 1.8.2-3-VC9 Installation

[siwelb61]

Hi!
I have a Windows XP machine that I've trying to get v1.8.2 install all day but can't get past the port conflicts. I tried installing this by turning off Windows Firewall, disable my antivirus software, adding an exception of the port in question to security setting (as suggested by XAMPP.org site) but nothing seems to work...frustrated and worry that I'll break something... I'm taking a PHP programming class & it's required that I download the XAMPP bundle & get it running on my local machine.
Can anyone help me get past the installation challenges I'm having? Any help is greatly appreciated! Below is the content from XAMPP control panel:

Hi siwelb61,

You did have Microsoft IIS Webserver running.
If you don't need this uninstall that windows component.

best wishes,

I don't know what Windows IIS server is...How can I disable it & why do I need it?

why do I need it?

Why you need IIS? I don't know. If you don't know what IIS is, then commonly you will not need it. Maybe a third party program has installed or activated it.
Why you should uninstall it? Because otherwise Apache will not start with it's default configuration.
