Gothic 3 patch latest or all

I just installed the game and it asked me if I wanted to install the patch 1.12, so I did.
my question is now: do I need to install all the other patches too or is this one enough?

edit: how do you sell only one thing of an item instead of the whole pack?

For the edit question: right-click ONCE on the stack of items, iirc.
For the first question: I think you shouldn't install later patches. And definitely not if you've already installed 1.12.

Orginally you had to install them in order, though I really haven't played in the last 2 patches, so I could have changed.
You should look at the size of all the patches.
My suggestion is to uninstall, reinstall adding each patch in order of first to the most recent patch last.

Are you downloading the patches yourself and then installing them from your PC or are you doing some automated update system?

You only need to apply the latest patch.
