Same comment as for the 32 bit version, the ISO file in this torrent does not appear to match the official distribution MD5: https://datapacket.dl.sourceforge.net/project/lxle/Final/OS/16.04.4-64/lxle_16.04.4_64.iso.md5
In addition to that, the official download page http://www.lxle.net/download/ does offer a torrent for the 64 bit version (but not for the 32 bit version) that contains an additional tracker: http://torrent.resonatingmedia.com:6969/announce
