DA:Origins, ModManager, .override installation

[Heljo19]

Hallo fellows, I have already searched the internet, but did not find a viable solution, so here we are:

I want to install a .override. Followed all instructions from the author, started the MM in admin mode, made sure that all paths are set up right (at least I think so).

not sure if you can read it, the blue lightened box says "show all installed". If I switch to "... uninstalled" it does not show up. So seemingly I successfully installed it.

But it is supposed to appear in the center now, so that I can make my configurations. But it does not. What might I be missing here?

Edit: If I drop the file in the "installed overrides" part or click right and go on "install" actually nothing happens at all.

Great thanks if anyone should respond. I would really like to get this game running with a few mods. And it feels like I "almost made it", so no point to give up there...
