Crusader Kings 2 v. 3.2.0
I had a lot of problems finding all pieces (and still haven't found v 3.2.1 but that's fine, I don't necessarily need it), so when I found all, I decided to upload it all as a single torrent.
Just install them in the presented order and it should work. Every previous update is necessary for the next one.
And don't forget to seed or I will declare war on you!
