Installation errors

I have finally found the problem but I dont know how to fix it.
Actually all the links work if I put index.php in the path.

By example, this link : www.dev.com/azezezez
not gonna work

But : www.dev.com/index.php/azezezez
will work

Have u any idea for fixing that ?

You need .htaccess file to rewrite url. Place it inside the same folder of index.php.

Code:

Options +FollowSymLinks
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php/$1 [QSA,L]
