Mario & Sonic at the Rio 2016 Olympic Games skeleton help

[Carpaccio]

Okay I cannot get pacpack to work no matter what version or game I use it on. Every single time I drag and drop, it just gives me the error 'pacpack.exe has stopped working' and just dies. with no output. Is there something I'm missing? Did I skip a step? Can someone PLEASE help me get the models of Sonic, Shadow, Eggman, and Eggman Nega? I don't even need the rigging.
