PHP4 - apache install problems

["Alan Hood" <a.hood@xxxxxxxxxxxxxxxxxx>]

I am trying to install PHP4 on my own Windows XP system running the Apache2 
server.

PHP is installed in c:\php

I have added the following to the httpd.conf
ScriptAlias /php/  "c:/php/"
AddType application/x-httpd-php .php
Action application/x-httpd-php "/php/php.exe"

When I try to run a script, e.g. 127.0.0.1/testphp.php, I get a 403 
'forbidden' error.

Can anybody tell me how to get rid of this.

Many thanks.
