Test tracert is working with the loopback:

2> tracert:host({127,0,0,1}).
[{{127,0,0,1},
  62,
  {icmp,<<8,0,188,171,192,189,0,0,32,33,34,35,36,37,38,
          39,40,41,42,43,44,45,46,...>>}}]

The default is to do a ICMP traceroute. You can try doing a UDP traceroute:

3> tracert:host({8,8,8,8}, [{protocol, udp}]).

Also test if traceroute or tracepath are working from the command line. If not, you'll need to allow traceroutes through your firewall.
