You have to install it through the terminal. Just open a window and type: - sudo gainroot - cd MyDocs (and depending on where you placed the files .documents in my case) - cd ..documents - ls (to see the files listed in the folder) - dpkg -i mafw-gst-eq-renderer.deb (to install the file) The file will be installed. If you encounter dependencies problem, after the install, type: - apt-get -f install (this will correct the problem)
