Installing Turck MMcache on win

Hello! I've downloaded "turck-mmcache-2.4.6-win32-php-4.3.4.zip". I'm running PHP 4.3.4 (InstallShield version) on Apache 1.3.23. The default setting for PHP was to run as CGI - but Turck readme said, it needs to be mod. OK, i've set httpd.conf. I've copied mmcache things into php.ini (c:\apache\php) under the other extensions part, and mmcache.dll into php/extensions. But when I run mmcache.php, it says that it's not installed. Then i've noticed that I have a php.ini in my winnt folder too (I think that's because i've installed "PHPTriad" first and then PHP 4.3.4). So I've updated it too but still nothing. What have I done wrong? Should I configure php too to run as a mod? Thanks in advance Veress Berci
