PHP not running

Hi, I am using windows 2000 with apache 1.3.29 and PHP 4.3.9 I am not able to run the php i.e. <?php echo "Hello World"; ?> does not display anything. When the apache server is killed it gives the following error [Thu Nov 11 11:47:36 2004] [error] Cannot remove module mod_php4.c: not found in module list I followed the following steps to install: Unzipped PHP added the line <LoadModule php4_module "c:/php/sapi/php4apache.dll"> to httpd.conf tried both php.ini-dist as well as php.ini-recommended as php.ini file ran apache tried to open a simple php file <html> <body><?php echo "Hello World"; ?></body> </html> the page came up blank! I am assuming that I am missing something very basic. any help will be greatly apreciated Fahad
