Mixamo animations imported into UE4 don't import

Whenever I import a mixamo animation, and I choose the mannequin skeleton, I press the button, and only errors. No import. I know I need to retarget the animations, but I can’t. I have no software for it, there’s no documentation, and a tool that was supposed to do it for me did. NOTHING.

I just want to make a game, Unreal.:skull::skull:

I suggest you to first get a Mixamo character and import in Unreal, then import Mixamo animations and choose the Mixamo character.
Once imported, open the Mixamo character and use the retarget function to match mixamo joints with the Mannequin joints.
Once you’re done, select all the mixamo animations you imported, right click > retarget anim asset > dulicatre and retarget

From there you’ll see a list of possible ( retargeted ) character, and you should see your mixamo character.
Select it and choose retarget, and you’ll have all your mixamo animations retargeted to the Mannequin.
