The port is occupied by another application already, thus WAMP cannot start. Run netstat -a -b to identify all processes with network connections, find those, listening on port 80 and 8080 (Skype, etc). Terminate those processes. Restart WAMP, all Servers should start now correctly. The other processes can be started again (Skype in particular will default to another port as the WAMP ports are now taken).
Solution #1
- Quit Skype
- Run WAMP
- Run Skype
Solution #2
- Go to tools (on Skype)
- Options/Advanced /Connections
- Uncheck the box "use port 80 and 443 as alternatives for incoming connections
Solution #3
- Under Config Files select httpd.conf
- Open it with notepad, find Port 80 and replace it with Port 8080
- Save it
