Just going to install advanced web ranking tool on leopard but the package doesnt ask for the root password so the install fails. Ive seen this problem with mpkg files before so i checked all my disk permisions etc but still wont install. I assume its a problem with the installer as i say ive seen this happen with other mpkg files so get a terminal – locate to were the app is and tpye the following
installer -pkg <packagename> -target <mountPoint>
IE
installer -pkg packagename -target /Applications
Asks for root password and installs the package 🙂
