XAMPP - Apache Instalation Error

Question

When ever I install XAMP I get this message

everything works fine but there is this message every time I install.

Answer 1

That means so other software is already listening to port 80 or 443 could be skype or iis shut that down then run the installer again,

Answer 2

Use use netstat -ao |find /i "listening" to find what process id is listening to the port, then use your task manager to see what process it is and stop it.

Answer 3

I assume this is a linux box, if so try sudo netstat -lnp |grep :80. It should let you know what process is using port 80. Based on the Process ID you should be able to further investigate if necessary. ie ps aux |grep <process id>

Replace <process id> with whatever number netstat tells you :)

Answer 4

Use tcpview to see what process opens port 80 or 443.

Answer 5

All you need to do is Add Port Exceptions in your Windows Firewall Settings for port 80 & 443
