The .json file has been updated again for the 2.0.40.1 installer.

Thank you for your effort. Is there a offline installer for the 2.0.37 Beta version?

Here you go:

https://cdn.gog.com/open/galaxy/client/2.0.37.384/setup_galaxy_2.0.37.384.exe

Thank you very much :)

My suggestion would be to use the online installer. Once it downloads the full installer can be found in

"%UserProfile%\AppData\Local\Temp". Just make a backup of the "GalaxyInstaller_*****" folder.

But given the update frequency of these launchers, may not be worth the effort.

A newer direct link for the offline installer;
https://cdn.gog.com/open/galaxy/client/2.0.43.71/setup_galaxy_2.0.43.71.exe
This is the version current as of the date of this post.

But it is weird, that this link can't be found in between some lines of text on a default gog.com site...

This isn't weird, the online installers are the super duper dope experience for the brainless mass of lemmings. Simplistic full offline setups aren't considered modern aka commercialistic enough. I don't like it too, but I'm nevertheless happy getting these setups, although finding them is detective work.

I don't think that someone who is using an online installer of whatever is brainless, especially not for a program that is meant to be as an online service like Galaxy.
I just would like to see more transparency on GOGs site.

The latest version: https:/cdn.gog.com/open/galaxy/client/2.0.46.133/setup_galaxy_2.0.46.133.exe

Obg meu amigo ! , Instalei aqui e agora funcionou !! , Obrigado !! S2

Many many thanks to lexluthermiester for this help!

It worked - i don't understand why at GOG no one has a clue why the webinstaller doesn't work and why no one at GOG came up with the idea to use the offline installer.

They seem to be quite clueless. Even after almost 4 weeks no reply from GOG!
Thats really no good customer relationship! You should work on that GOG!

Yeah gog galaxy installer isnt finding the internet. I reckon its internal link to find the gog server to download the files is down.
