extension-dir not working...PHP4/Apache2

[onlinegs]

Hey, I am trying to load the php_gd2.dll library, I uncommented it, and then set the extension_dir to D:\PHP\php-4.3.4-Win32\extensions

but when I restart the Apache2 server I get the following error:
Unknown(): Unable to load dynamic library 'D:\PHP\php-4.3.4-Win32\extensions\php_gd2.dll' - The specified procedure could not be found.

That is the correct path to the php_gd2.dll as far as I can tell, the path to Apache2 (if it helps) is D:\Apache\Apache2\

And, my php.ini file is located in C:\WINDOWS.

TIA, Bryce

It still isn't working, I upgraded the the most recent version of Apache2, but still no cigar.

Any and all suggestions are appreciated.

TIA, Bryce
