I've just installed XAMPP on my machine at home (Windows XP). The installation seems to have gone OK, but when I try to start Apache I keep on getting the error message
(0510048) only one usage of each socket address (protocol/network/address/port) is normally permitted. :makesoc could not bond to address 0.0.0.0:433. No listening sockets available, shutting down.
I'm sure nothing else is running. I've completely uninstalled all previous versions of Apache and I don't have IIS (or whatever the Microsoft thing's called) on the computer as far as I know.
Please help!
