Firstly after installing Linux mint 10, update system using the update manager.
After copy contents on the APTonCD from the packages folder except (aptoncd-metapackage_date.deb) to /var/cache/apt/archives (remember to open this with sudo nautilus in terminal)
Now open Synaptic package manager select packages to install. remember to connect to the Internet so that packages that you don't have will be downloaded before install.
This should work fine.
