APACHE needs port 80 - MAMP

Question

I want to run MAMP on my Windows 8.1 pc, but when I start the servers, it says:

'APACHE' needs open port '80' which is already being used by another 
service or application. Please reconfigure 'APACHE' to use free port.

Changing the port to something else doesn't help.

I also found this post - https://superuser.com/questions/960023/port-80-already-in-use-after-windows-10-upgrade - suggesting disabling the IIS service, which worked perfectly for me

Answer 2

Hey On Windows 10 I Ran into the same issue.. I found a way that is a guarantee fix... Go into controlpanel -> system security -> windows firewall -> on the left pane there is advanced settings.. click that. -> then add new inbound rule (on the left pane click inbound... then new rule on the right pane.) -> then follow the wizard as program and select mamp from C:/MAMP I believe. Then you are Golden!! Hope this helps all those out there with the new windows 10. Hypertextie

You can change MAMP ports in Preferences -> ports, like a screenshot below

Answer 4

Thru some web searches, I discovered that other windows services are know to be using Port 80. In Windows Search (via Windows Start), type 'services', stop one of these services below en test again till it works. Do not forget to restart it later !

• SQL Server Reporting Services
• Web Deployment Agent Service
• BranchCache
• Sync Share Service
• World Wide Web Publishing Service
• Internet Information Server

Answer 5

Start windows command line and then run netstat -aon | findstr :80 You will see line with process that is using port 80
