The latest C++ version is not always the one that's needed or missing.
But it was just a long shot anyway. If I did experience the problem, I could try to find a way to fix it.

You could use Dependency Walker on the dll you named and also on the Galaxy main executable to see what's missing.

I have the exact same issue as OP the exact same error message in reliability monitor (multiple instances of the errors) as OP and many others here. This is clearly a gog issue that needs fixing. I wasn't going to post as I thought it was something wrong with my new rig I upgraded to a ryzen 7000 with a rtx 3080 and thought maybe gog is having issues with my new CPU soon as I googled the issue I found this post. Why hasn't gog not done anything about this?

Yep same issue for me. Playing cyberpunk and game crashes randomly.

I doubt that's related, but you can downgrade GOG Galaxy and find out for sure.

We shouldn't have to lobby Galaxy of Games (GOG) to fix their own platform with critical errors galore.

But if a change.org petition is what they need before they acknowledge these flaws, their slow response times and admit their faults it may lead to them actually fixing them properly and permanently then we may as well start there.

One thing to be independent, another for GOG to detach themselves from all accountability and responsibility.

I really do wonder how many of us have to submit tickets for them to get on it, fix the damn problem and not blame the crashes on firewalls and antiivrus systems...

Big thumbs up for you! Well said friend...

GOG Galaxy wants to compete with EA app for the title of the worst platform to manage and download video games.

I have the same issue. Filled my event viewer with 170 crashes...

What I did to hopefully mitigate this.

I installed the old version, then I opened C:\ProgramData\GOG.com\Galaxy\redists and deleted GalaxyUpdater.exe - then I just renamed one of the .dll's there to GalaxyUpdater.exe and set it to read only.

With any luck, it will not try to update the client to the new version now.

Seems to have done it.

You can see by the screenshot when I downgraded the client :P

this workaround was already mentioned a month ago ( e.g. https://www.gog.com/forum/general_beta_gog_galaxy_2.0/constant_application_crashes_galaxyclientserviceexe/post21 )

But what we need is not a workaround , we need a bugfix.

I wonder anyway why GOG only offer a BETA version for users. For me personal, I have this installer only for one single game installed and with such kind of issues and how they handle such kind of issues , I assume on my pc will not a second game installed from that platform ;)

I have 38 instances in Reliability monitor of Galaxy Client Service stopped working. I am part of the club, yes?


The only odd thing I found was that 2 services were not running; they were both set to disabled ?

GalaxyCommunication
GlalxyClientService

Alright wtf today i was playing cyberpunk for like 2 h. Then game crashes, i open event viewer and BOOM 78 errors 78!!!
from galaxy client service. Like wtf

I installed GoG a few days ago:

The GalaxyClientService service terminated unexpectedly. It has done this 24 time(s).
