Attach animation on Unity 5.3?

Question

Unity

Good day tostorians!
I ran into one very intrusive problem in Unity 3D, most likely it arises due to very little experience in this program, but I have to write here after long dances with tambourines.
I found a 3d astronaut character for my game:
https://www.cgtrader.com/free-3d-models/character-... - here is a link to it.
Installed the plugin:
MOVEMENT ANIMSET PRO VERSION: 1.25
u3d.at.ua/load/animacija/movement_animset_pro_vers... - here is a link to it, and I wanted to attach the animation from there to my character because I had previously used it and everything turned out pretty well, but does not come out on the new version of UNITY 5.3
I do everything in order, in the animator I create an animation and attach Idle there and nothing happens.
Tell me in what direction to think gentlemen.

Answer 1

you can’t just take any model and any animation and they will work woo a la. They won't work: different dice, different names, etc.
Ask someone to animate your astronaut in 3d max and then throw everything (model + animations: can be one file or set) into Unity and then do Idle and so on
