htaccess Deny from all and 500 Internal Server Error

I want to restrict direct access to a specific directory (and all the files inside) on my local server. The directory is: C:/Server/www/project/html/

I've tried the following code (.htaccess is placed in www directory - /project/html/ doesn't work too):

<Directory "C:/Server/www/project/html/">
    AllowOverride all
        Order Deny,Allow
    Deny from all
</Directory>

However, it causes 500 Internal Server Error and I can't understand why.

Apache error log:

Check Apache error log for exact error description.

In any case -- the reason for this error is simple: <Directory> directive CANNOT be placed in .htaccess file -- only server config or virtual host.

for me it required enable headers module to apache
