Update Only Procedure [Alternative]
Reusing Files You Already Have for Faster Download
If you already have another version of the game, no matter where it comes from, no matter the version number, or even if it's multi language or English only, you can optionally do the following if you want to speed up the download process by reusing the files you already have in your computer!
The instructions below are for Tixati, but you will likely be able to do the same if using another torrent client.
Once you start downloading you should have a similar screen like the one below. You need to select the torrent, right click on it, choose stop to make Tixati pause downloading (mine was already complete, therefore it shows as seeding, yours will be downloading and with a lower percentage in your progress column until it's done).
As you can see above the folder structure is similar to what you have on your local copy of the game. What you will do next is to reuse the files you already have on your computer, so you don't need to redownload them, saving you many hours of wait.
To do that, you'll have to open your local copy of the game on Windows Explorer. In my case I use the default
C:\Program Files\The Sims 4 folder, but your copy of the game can be located anywhere else according to how you set it up previously (Origin's version can also be used as a "source" for this step, by the way).
If you look at the folder structure below you'll see it's VERY similar to the one within the torrent. What you want to do is to select everything (left click any of the items just once, then use Ctrl + A so select all items), then copy (Ctrl + C or Right Click Selection, then Copy).
Now, back to your torrent client, you want to right click on the folder The Sims 4 shown below, then on Open Folder.
Double Click on The Sims 4
Now you can press Ctrl + V (or right click on an empty space, then select Paste) to Paste the previously copied files:
Enable the check mark to "Do this for all current items" when you see the dialog below, then click on Yes.
Once you're done copying / overwriting the files, open Tixati again, then right click on the torrent you're downloading, then Local Files, Force Recheck.
That will make Tixati compare the files you just wrote with the ones that should be downloaded. If they're the same, they'll be reused, if they're different, they'll be discarded automatically, that way Tixati will only download what you really need on the next step.
Once the Force Recheck procedure is done (it may take a few minutes to process everything), you just need to right click the torrent again, then Start.
Depending on which files you already had this will speed up your download considerably. Once your Progress Bar is at 100% your download is complete and you can move to the next page for the next step of this tutorial!
