bin-3 give an integrity check error if downloaded from the browser. You can download it with galaxy to avoid that problem (not sure if the integrity check is a false positive).
The only real problem is that you need to download all the parts again with galaxy (since you cannot get only one part), but I tested it and only bin-3 give an integrity check error.
At least now the game is drm-free.

This is why I hate that the GOG Downloader was abandoned in favor of GOG Galaxy for those of us that perfer to download the offline installers and what to make sure the files are not corrupted from a browser download. I am glad the new GOG Galaxy now lets you quickly download all the Goodies at once but it's still a pain getting to the game you are looking for when there are game updates or even being informed if there are any for games that are not installed. Also you can always try copying the files to the folder that Galaxy is downloading to and it should reverify them and only download what it needs from there or at least I think I saw the old Galaxy do that.

I downloaded from the browser and verified my files through gogrepo and during the installation process, and I didn't receive any validation errors. Can you compare your md5 hash with mine? (I scanned both files because I wasn't entirely sure whether you meant the main game or DLC bin-3)

setup_deus_ex_mankind_divided_1.19_hotfix_(38078)-3.bin
md5: F4F4C3513FE07718301FE9F5F3F4B706

setup_deus_ex_mankind_dividedtm_dlc_-_season_pass_1.19_hotfix_(38078)-3.bin
md5: 5D42F689C3310FBF0D2A3AF0CA18E00F

I verified them with the integrity check included in the installer of gog, you can try too if you want.
The corrupted bin is not the dlc one (it's not possible to do integrity check during dlc installation) .
I will download it again as soon as I can from the website to tell you the md5... I already keep only the not corrupted one from galaxy (after that I uninstalled galaxy...).

Just to be sure - game itself does NOT include Denuvo anymore? I refuse to let Denuvo install on my PC no matter what.

It wouldn't be on sale here if Denuvo was still a thing.

the galaxy communication service runs in the background ever since uhhh i dunno 2016 or so KILL that service you ll see it ll not effect the game at any stage, the launcher itself is another service running, check it if you use galaxy.

the Games are DRM free you OWN them, you also say VC++ Runtimes are DRM? Just because games need them?
You claim Net Framework is DRM just because it is needed to RUN in the background?
NO

It is as i said as long as the game starts without Internet and without Galaxy running (THE LAUNCHER), it is
as it should be, clearly without and DRM measures.

If that service would be DRM then the game would be killed the moment you kill that service, that never happend
to me. As long as i test the purchases i make on GoG. You may ask the support why they decided to
let the communication service run in the background.

PS: Check the snippet i made, as you can see there the service is killed and DE MD is running.

GalaxyCommunication.exe is a part of Galaxy. If you don't have Galaxy installed, this service isn't present on your PC.
It wasn't the game itself which had the DRM. The base game itself was running fine without GalaxyCommunication.exe. It was the Season Pass DLC. Check my screenshots. The first one with GalaxyCommunication.exe running, the second one without.

GalaxyCommunication.exe was never necessary to run games from GOG. The Offline Installers don't have this service included. It was a bug and GOG solved it already. Both, base game and Season Pass DLC are now DRM free.

Again, the game was running fine. The DLC was faulty. If you don't have Galaxy installed, there is no GalaxyCommunication.exe which was needed to run the DLC content.

It stays running because of Galaxy multiplayer so you can play games with Galaxy implemented multiplayer without running the Galaxy launcher.

Your screenshot shows the main menu of the game. The DLC content is in the Jensens Storys submenu.

sounds like a bug to me, the thing withthe communication service happend to me
with a offline installer / backup i downloaded. Ever since that happen i test if the
Games truly work standalone, that service appears to be a wrapper to provide
the communication wit galaxy overlays and so on, that is NOT DRM when the Launcher
itself doesnt start, with the game.

Trust me, it would be DRM when the Service would interfere with the game in any way.
That never happend to me and as shown i even can kill the service and the game runs
fine.

just for you DLC choosen Criminal Past as you can see the service is shut down, galaxy
as a whole is shut down and i can start it. That is not what a DRM copyprotection does,
the the communication service rly would be DRM it would shut down the game with a
error msg as soon as you KILL it, i even can kill it before hand and the game starts
anyway.

If you have doubts ask the GoG Staff about it, in case you want to know WHAT EXACTLY
that service does.

I DO know for sure it does not prevent you from OWNING, PLAYING the games you buy on GOG.
Neither it forces you to use the launcher or being connceted to the internet.

I am not sure WHY it does bug out for you, i just can confirm that the game is 100/% DMR free
for me. *shrugs*

PS: So the service is to provide MP functions if necessary, well then it makes sense, not so
much on pure singleplayer games... but Deus Ex MD isn t "pure" per se. But MP Mode
is not DRM, that is what this thead is about.

The corrupted part is fixed now.
Support told me it was actually the same file as galaxy but I think there was some kind of temporaly problem from the browser (not on my end... Like I said I downloaded the fie multiple times).

I only checked the MD5 this time so I know it's the correct file.
In the end the good thing is that you can use the browser to download all the files.

Yes that is what GoG does, just being a STORE first and formost and JUST that.
just like a retail store of the "good old days" where we owned ALL of our purchased
games. (yes yes i know even back the EULAS said otherwise, yet still what i buy is mine)

I downloaded and installed the game 6/13/20 from the offline installers, and see no trace of DRM or DRM-like software after installing. I am fine with the missing single-use and other consumables not being there - and it's true still, some of the consumables parts of the DLC aren't apparently available in the game but they are listed on the product page. My bigger problem is the game crashes often. Honestly, the whole mess with the DRM removal based on converting a steam version makes me curious whether that is related to why the game is so unstable and crahes frequently.
