problem loading mysql dlls

[Bob Newsome <bobn@xxxxxxxxx>]

I am trying to upgrade an Apache 2 PHP installation on XP  Home from an 
earlier version of PHP 5 to version 5.2.4.  The previous version was 
working fine.  Now I am getting the following message when starting Apache:

[18-Sep-2007 18:11:52] PHP Warning:  PHP Startup: Unable to load dynamic 
library 'c:\php\php524\ext\php_mysql.dll' - The specified procedure 
could not be found.
in Unknown on line 0

phpinfo.php runs fine and returns the following


Configuration File (php.ini) Path 	C:\WINDOWS
Loaded Configuration File 	C:\php\php524\php.ini

extension_dir 	c:\php\php524\ext 	c:\php\php524\ext

ENVIRONMENT
Path
C:\php\php524\ext;C:\rails-prod-win\ruby\bin;c:\ruby\bin;c:\program 
files\imagemagick62;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\Program 
Files\ATI Technologies\ATI Control Panel;C:\Program 
Files\QuickTime\QTSystem\;

I looks to me like all of the paths for finding the dlls match. The 
php_gd2.dll  is uncommented in php.ini,  but it does not produce and 
error message and gd is enabled in the phpinfo.php output.

I have reloaded the php directory from the zip file, but this does not help.

What should I try next?

Thanks,
Bob Newsome
