php/apache error: Cannot remove module mod_php4.c: not found in module list

Hello, I've installed Apache 13.22 and it works. Then I installed PHP410 and configured the config httpd.conf as this: -------------------------------------- LoadModule php4_module c:/php/sapi/php4apache.dll AddType application/x-httpd-php .php -------------------------------------- Also I have copied php's dll to system32/ directory and php.ini to windows/ dir. and when I'm trying to access .php files I get the browser's File download window. And the string in the subject line at apache's error.log. It is all running under WinXP. What should I do? Thank you, Serge.
