Welcome to this board, first of all... You should download and install your software from the nabilo server through the blue button? (yellow) can't remember which one actually. If you want to ftp it than it's a bit more complicated. The binaries (executables) will go in /usr/bin while the configuration files under /var/keys.
However I urge you to use the download server of whatever image you are using, even more so with nabilo images
