Fatal error: Cannot declare class XMLParser, because the name is already in use in C:\Apache24\htdocs\inc\class_xml.php on line 17

I'm not that familiar with hosting webservers, but I hosted one using Apache24 in order to start workign on making my MyBB forum. I followed the install guide to the letter, but when i try going to localhost/install on my browser, I get the error in the title:

Fatal error: Cannot declare class XMLParser, because the name is already in use in C:\Apache24\htdocs\inc\class_xml.php on line 17.

Using Command F, I went through every PHP file in the \install directory, and none of them seem to be declaring XMLParser. What should I do?
