PHP extensions on Win32

I have been installed the PhpTriad(phpgeek.com). It's run on php 4.0.5.
I downloaded from php.net the lattest version 4.1.* of php and installed it.

When I operated php_gd.dll extensions from php.ini and exactly specify where "extension_dir="

When I execute this function [ phpinfo(); ].
After it, I begin to got this kind of msg:

I have this and work ok;

; Directory in which the loadable extensions (modules) reside.
extension_dir = C:\php\extensions

I already specify as I wrote:
My is: extension_dir=C:\apache\php\extensions\

Probe with extension_dir=C:\apache\php\extensions

Already, probed.
Nothing.
