Hello,

The DLC "Treasures of the Sun" is not recognize by game, if i use setup offline for installation
And with GOG Galaxy, the download stopped in 98%, i can't install with the launcher

Other people have a similar problem like this ?

Yes. The DLC download in languages other than English is broken for me too.

Yes, I can also verify that there are problems with the offline installer of the DLC. I've downloaded and installed it OK but it's not showing up in game. I've just put in a support ticket so hopefully it'll be fixed soon.

Oki, thanks for you
I guess we have to wait for GOG to do something

Ok, it work, now !
Download with GOG Galaxy, i don't think it's fix for the setup offline in the site for the moment

Thanks for the info. Hopefully the offline installer will be updated soon so I can get to play too :)

Reading the Steam forums, it may be it never shows up in the main menu but is accessible in-game once you reach a certain part of the main campaign. Does anyone have any first-hand experience of this?

Hmmmm.

Do any Steam saves work in the GOG version?

One could always try their Treasures DLC saves from Steam version and toss them into the GOG version, if it would actually work & load.

A: if you paid for a game, and you meet the requirements, it should work. if it does not, GOG should find a solution.
B.IMHO, if DS3 does not work, you are not missing much, since I dislike DS3 a lot.

The message alert of DLC appears in early game, juste after started it
For having finished the game many times, I confirm it

But you can download DLC with GOG Galaxy, You getting a offline setup, It's like you download from the site

Until GOG installs it on the site

The DLC installer download has been fixed. It show up in the main menu of the game as purchased.

Unfortunately not yet updated if you don't use Galaxy and rely on the offline installers.

I have all 3 games on Steam, and now GOG.

My save from playing the expansion will not load, because game says I don't have the DLC (DLC Installed with GOG Offline installer).

Steam version does show the DLC in the menu, as purchased, so I expect GOG will do the same, once fixed.

So I did a fresh install via Galaxy and the DLC properly shows up in the "Downloadable Content" item in the main menu. There's also an entry in the quest log for it as soon as I started the game.

I tried the same thing on my laptop yesterday, using only the English offline installers, but there, the DLC apparently isn't installed properly. :(

Also, the file sizes confuse me. The English version of the DLC installer is 203 MB, whereas the German version (haven't tested that yet) weighs in at 319 MB.
