go to user/your username/appdata/roaming/strive for power2 and there you should see 2 folder 1 with the name Bodies and 1 with the name of portraits. You only need to unzip the contents there as is. The body pack go in the Bodies folder the portrait pack go in the portraits folder.

Technicaly, you can put them anywhere and select the portrait/body folder paths from in-game too.
