Wamp - Installed php5.2 Addon - Icon Stays Yellow

I originally installed a recent version of wamp (php 5.3) but I need to use php 5.2 for my current project. I downloaded the addon for php 5.2 and installed it. Then I stop all services and in the wamp menu I do

PHP -> version -> 5开发者_高级运维.2.11

I restart. Now wamp goes from red to yellow, but never goes from yellow to green. I don't see anything relevant in the apache error log. How can I troubleshoot and resolve this?

Thanks, Jonah

I found workaround. You need to install 32bit Apache addon. And use it to work with 32bit PHP.

i managed the same situation, IIS uses the same port 80 or your old wamp server(it didn't uninstall correctly). if you can't unistall it. you should change wamp port in httpd.conf

1.find these lines :

 Listen 80
 ServerName localhost:80

2.change to

 Listen 81
  ServerName localhost:81

3.restart all services.

4.enter this address on your browser. localhost:81
