The original version of the addon, by Phymec should still work in 2.79. You can get that version here.
My version of the addon does add a few things to organising the scene though, so the colliders generated by the original addon don’t have particularly great names. However, I’ve not really got time to port to 2.79, but the code for both addons is available if anyone feels like getting their hands dirty. Let’s just hope the FBX bundle addon is updated soon
