Also on Apache 2,4 you may need to add this to the directory directive in conf, in case you decided to include httpd-vhosts.conf.
By default you can install wamp in C:\ but still choose to deploy your web development in another location.
To do this inside the vhosts.conf you can add this directive:
<Directory "e:/websites">
Options Indexes FollowSymLinks MultiViews
DirectoryIndex index.php
AllowOverride All
<IfDefine APACHE24>
Require local
</IfDefine>
<IfDefine !APACHE24>
Order Deny,Allow
Allow from all
Allow from localhost ::1 127.0.0.1
</IfDefine>
</Directory>
