"File not found" error under Apache 2.2 when it try to loadmodule php5apache2.dll

["Laurent PIERRE" <laurent.pierre@xxxxxxxxxx>]

Hello,

I'm under WinXP SP2, with server Apache 2.2 installed and working. I've 
installed the latest version of PHP and I've modified my httpd.conf file to 
add these lines :

LoadModule php5_module php/php5apache2.dll
AddType application/x-httpd-php .php

My Php install folder is behind my main apache folder.
When I restart Apache server, I obtain this error

Cannot load the E:/Web/Apache22/PHP/php5apache2.dll into server. Specified 
module could not be found.

Of course, this path exists and file too. I can see it. I've tried with all 
lower case. I've quoted path too... It's completly crazy,
but I cannot understand what kind of subtility there is.

Maybe, someone could be help  me.
I'll appreciate infinitly.

Thank  you for your help.

Laurent
