Joomla templates

Hello... I have some problems while installing modules and components with comuna quickstart. I have upload the quickstart comuna to my webserver, but for that, the components and modules must be installed, and i have tried to install them from the joomla directory, but still i get this message:

Installation file not found:
/data/members/paid/h/e/hemels-licht.com/htdocs/www/administrator/components/com_installer/component/

can this be simply working?

greatings,
