Apache Friends Support Forum

I'm new to this so sorry if ...

Installing XAMPP, the control panel eventually said that Port 80 was in use by "unable to to open process" with PID4. I don't know how to unblock this port. Alternatively, I don't know how to induce XAMPP to use another port. I clicked the "config" button and then the "service and ports" button which referred me to config files. But I don't know my way round well enough.

I bet there is an FAQ dealing with this somewhere on the forum, but I can't find that either ! (bumbling twerp )

Hi David,
you need to allow apache to use port 80 in your firewall settings and disable IIS if its running.

Good luck
