Removing Itunes from computer

I originally got the message "is not a win 32 application". I followed all the troubleshooting steps, however, itunes was never installed. When I click on the"setup itunes exe" is when I receive the WIN 32 message. Therefore, when I go to remove programs, I tunes is not an option. The setup is still on my computer but how do I uninstall that? I need to do this to continue the troubleshooting. Also, anyone know if its possible that Itunes is not applicable with XP Media Edition.
