Could anyone help me?

I try to run php on win 98 (PWS). It looks like php.exe works but when I try to run some test page with Internet Explorer (test.php) on my localhost I just get this error message -------- HTTP Error 403 403.1 Forbidden: Execute Access Forbidden This error can be caused if you try to execute a CGI, ISAPI, or other executable program from a directory that does not allow programs to be executed. Please contact the Web server's administrator if the problem persists. --------- I have tried to use php-installer and I have installed php manually (zip version) according different instructions but nothing seems to help. I would appreciate if you could give some comment. Thanks Kari
