    We cannot download the full version automatically, as you require a license.
    Once you bought a license, you need to add your downloaded version to the nix store.
    You can do this by using "nix-prefetch-url file://\$PWD/WorldOfGooSetup.1.41.tar.gz" in the
    directory where you saved it.

    Or you can install the demo version: 'nix-env -i -A pkgs.worldofgoo_demo'.
