WAMP / Apache Alias security issue

im trying ton install magento.

1. I have downloaded latest 1.9.1 magento and extracted it.
2. copied the mageto folder to here C:\www\magento
3. created an alias magento with directory C:/www/magento
4. restarted the server

when I browse localhost/magento i get this error

Forbidden

You don't have permission to access /magento/ on this server.

Apache/2.4.9 (Win64) PHP/5.5.12 Server at localhost Port 80


I have searched on the net and I check this file which says allow already

C:\wamp\alias\magento.conf

Alias /magento/ "c:/www/magento/"

The contents are as below

<Directory "c:/www/magento/">
Options Indexes FollowSymLinks MultiViews
AllowOverride all
Order allow,deny
Allow from all
</Directory>


So what could be the problem ????
