I Installed WAMP Server Successfully.
My OS is:
Windows 7 32-bits
2.2E ( 32bits & php 5.3 )
You can check if the port is being used by other program using WAMP menu -
Click on WAMP icon
select Apache -> Service -> Test Port 80, this will check if the port is used by any other program
Also do this
select Apache -> Service -> Install Service, this will make apache use port 80 if the port is not already used by any other program like IIS or Skype
Restart the WAMP see if the problem is fixed.
If port 80 is already used by some program, then you can choose other listening port for WAMP. To do this -
click WAMP icon -> Apache -> httpd.conf
listen 80 (where 80 is port number, it can be different on your system)
Now change that to something else like 3333, you can access WAMP homepage by typing
127.0.0.1:3333 in browser's address bar.
If you want WAMP to use port 80, uninstall the program that is using port 80 and then do things stated in step 2 or you can change port in that program's setting, also check
httpd.conf file for
listen [port] line.
