PHP 4.3.1 Installer - Windows 98 - PWS HELP!!!

I have installed PHP 4.3.1 Installer from http://www.php.net/downloads.php for Windows98 and PWS. After installation, I received 403.1 Error so I set the MS PWS <Home> virtual directory to set for Read, Execute, and Scripts access. PWS sever is running and it runs other web content (both html and ASP) fine. But now I get a Server Not Found page when accessing my PHP Test page (http://localhost/PHPtest.php). I have checked the registry and php.ini file located in C:\windows\ and the settings seem to match all the areas covered in the "manual install" instructions at the http://localhost/PHPtest.php site. So, I assume the install wizard did its job. I have also tried to change the cgi.force_redirect to both 0 & 1 but makes no difference. I have also tried adding the PHP directory as a virtual directory with all permissions but that doesn't work either. The php4ts.dll is located with the php.exe file located on C:\php\. Can anyone suggest anything else to try to get PHP running on a Windows98 and PWS platform? Thanks in advance.
