PHP - Problemas para configurar PHP4

Hola a tod@s ,q tal?
He instalado y configurado Apache bajo Win Me, sin ningun problema, el problema a surgido al intentar configurarlo para utilizar PHP4, me da este error

Forbidden
You don't have permission to access /PHP4/php.exe/prueba.php on this server.

Apache/1.3.12 Server at http:// Port 80

Alguien puede darme alguna idea de a que se puede deber...

gracias por adelantado

Es evidente que el nombre del directorio del sitio web no tiene los grants (privilegios) necesarios.

Puedes cambiar la carpeta y listo! Aqui te mando una copia dura para que lo estudies del archivo de configuración del apache:

#
# DocumentRoot: The directory out of which you will serve your
# documents. By default, all requests are taken from this directory, but
# symbolic links and aliases may be used to point to other locations.
#
DocumentRoot "C:/Archivos de programa/Apache Group/Apache/htdocs"

#
# Each directory to which Apache has access, can be configured with respect
# to which services and features are allowed and/or disabled in that
# directory (and its subdirectories).
#
# First, we configure the "default" to be a very restrictive set of
# permissions.
#

# OJO ESTE LO CAMBIE YO PARA TENER ACCESO A TODO EL #DISCO DURO.
<Directory "c:\">
Options FollowSymLinks
AllowOverride None
</Directory>


#
# Note that from this point forward you must specifically allow
# particular features to be enabled - so if something's not working as
# you might expect, make sure that you have specifically enabled it
# below.
#

#
# This should be changed to whatever you set DocumentRoot to.
#
<Directory "C:/Archivos de programa/Apache Group/htdocs">

#
# This may also be "None", "All", or any combination of "Indexes",
# "Includes", "FollowSymLinks", "ExecCGI", or "MultiViews".
