PHP install on Windows98 and PWS

I have installed PHP (using the install wizard and files from http://www.php.net/downloads.php on Windows98 and PWS. The PWS <Home> virtual directory to set for Read, Execute, and Scripts access. PWS sever is runing and it runs other web content (both html and ASP) fine. But I get a HTTP 500 - Internal server error when accessing a page (http://localhost/PHPtest.php) containing <html> <head> <body> <p>PHP Test</p> <?php phpinfo()?> </body> </head> </html> I have tested the PHP executable with c:\PHP\php.exe -i and it dumps the info file just fine. I have checked the registry and .ini file and the settings and they 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. Can anyone suggest anything else to try? Or how to get PHP running on a Windows98 and PWS platform? Thanks in advance. Keith E. engelhk@wor.rr.com
