problem starting php with sapi in win xp

Hi, I'm trying to setup PHP 4.2.3-Win32 as a sapi module into Win32 apache client (2.0.42-win32-x86-no_ssl) under windows XP downloaded the zip file from the php.net website, and then extracted the contents into c:\php\ (such that php.exe is in the root of that dir). Then I copied all the dlls into windows\system folder as per instructions, added the 3 lines of code: LoadModule php4_module c:/php/sapi/php4apache.dll AddModule mod_php4.c AddType application/x-httpd-php .php to the begining of httpd.conf file, and when i try to start the server it says: "Cannot load C:/PHP/sapi/php4apache.dll into server: The specified module could n ot be found." meanwhile C:/PHP/sapi/php4apache.dll is exactly where it's located on the hdd Thank you Eugene
