If wamp is running make sure no other program conflict Wamp such as IIS, Microsoft Web Deploy, SQL, Skype, Zonealarm, firewall/antivirus, NOD32, Eset, any web related program including Remote Desktop, Teamviewer ...
IIS and Apache/Wamp are both web server and might conflict in some way, so you have to disable IIS in order for Wamp to work
Disable IIS in Windows Vista/7
- Control Panel
- Programs and Features
- Turn off windows features on or off
- Make sure the Internet Information Services is not checked.
Disable IIS in Windows XP
- Control Panel
- Add and Remove Programs
- Add/Remove Windows Components
- Make sure the Internet Information Services is not checked.

- (Re)Install Wamp Server
Checking Your Host File
Windows uses a host file to resolve IP addresses, you will need to ensure that noting is conflicting or blocking it running on the local host. Edit this file:
C:\WINDOWS\System32\drivers\etc
Delete anything in this file and have only this line below and nothing else other than
127.0.0.1 localhost
Applications Conflicting on Port 80
Some applications are naughty and decide to run on port 80 one of these programs are Skype. To ensure your chit chat program is not interfering with your WAMP follow these easy steps.
- Open Skype
- Tools
- Options
- Advanced
- Connection (Uncheck use port 80)
- Restart Wamp
Consider Trying Other Ports
Wamp allows you to change the ports that the HTTPD service runs on, you can always try changing the port to see if that works for you. I recommend trying port:8080 and testing localhost:8080 or 127.0.0.1:8080 in your Browser.
