Example Humanoid Setup

For the purposes of this tutorial I just extracted captain from the game and set him up as a humanoid, so replace captain in this with whatever you are trying to make humanoid.

Set your Blend/FBX file in Unity to be Humanoid.

Click apply and then click configure

Once you click that, you will be presented with something that looks close to this. In the case of captain, Unity was able to auto set him up so we can just close this out. However for your character you might need to do some adjustments, just make sure there are in T-Pose before you finish.

Then you are ready to implement into your game, to double check that it works, click on a humanoid animation, then drag the model into the animation preview window. If this works, you should see your model animating.
