Win Installation Issue and Apache2 for Win

WinXP Home, SP1 Hi, I installed Apache 2.0.48 and PHP 4.3.4 installer package. Apache worked flawlessly before attempting to install PHP. When I attempt to start the Apache service after the PHP installation, the Event Viewer shows an error of: The Apache service named reported the following error: >>> Cannot load C:/PHP/sapi/php4apache.dll into server: The specified module could not be found. . Per the installation instruction in install.txt that came with the Windows binary installer, I made sure that the appropriate .dll's were in the SYSTEMROOT folder, and also alongside where apache.exe is run from (c:\program files\apache group\apache2\bin). In the c:\program files\apache group\apache2\conf\httpd.conf file, I added per the install.txt: ### For PHP4 for windows: # LoadModule php4_module c:\php\sapi\php4apache.dll AddModule mod_php4.c AddType application/x-httpd-php .php # If I comment out the "AddModule mod_php4.c" portion, the Apache server starts okay. It's only when it's not commented out. I looked all over for the "mod_php4.c" file. Should there be one? Testing of PHP fails with a simple page of <?php phpinfo();?>. TIA. -Mike R.
