The available installer downloads the necessary files (somewhere) and then proceeds to install Galaxy 2.0. Is there a complete offline installer that directly installs Galaxy 2.0?

Thank you. Is there anywhere I could have found that link? The Galaxy page only seems to point to the web installer.

A German website has Galaxy in their download area and the link pointed to this URL. But I have no idea how they found that address. I haven't seen in anywhere on GOG.com either.

Here's where I got it from: https://www.computerbase.de/downloads/games/gog-galaxy/

Thanks for the link, the "download an installer that downloads the software" method of installation always seemed crazy to me, especially when it is less reliable than installing the entire package. I have tried 3 times to use the default installer and wasted 600MB on a metered connection trying to install this, but the offline installer worked OK.

The link I posted is already outdated because they released another update.
So ... new link including the most recent "Hotfix": https://cdn.gog.com/open/galaxy/client/setup_galaxy_2.0.16.187.exe

Where did you find this? Will anyone else who wants to use the offline installer have to look for the links in the forums instead of a proper website?

Go to to see the JSON file containing the current version number, download URL, and MD5 checksum, for both macOS (OSX) and Windows.

Look for the key-value pair titled "downloadLink" to see the URL for the offline installer.

2023-05-20 - Edit to include advice for escape sequences, and to tidy up some ambiguous language

Windows doesn't appear to ship with a built-in port of sed, but PowerShell does have a "replace" function. If you want to use built-in tools without downloading any other software...

If you're on Windows (and have PowerShell), you can use a PowerShell command to pull down the file and strip out all the "\" characters, leaving you with a ready URL for downloading:

$(Invoke-WebRequest -Uri 'https://remote-config.gog.com/components/webinstaller?component_version=2.0.0') | % {$_ -replace "\\", ""}

If you're on a Mac, sed is included, so this may be of help:

curl https://remote-config.gog.com/components/webinstaller?component_version=2.0.0 | sed s+'\\'++g

Example output without stripping "\": https:\/\/content-system.gog.com\/open_link\/download?path=\/open\/galaxy\/client\/2.0.64.31\/set up_galaxy_ 2.0.64.31a.exe
Example output after stripping "\": https://content-system.gog.com/open_link/download?path=/open/galaxy/client/2.0.64.31/setup_galaxy_2.0.64.31a.exe

So the latest download link from alexmorris link is https:\/\/content-system.gog.com\/open_link\/download?path=\/open\/galaxy\/client\/2.0.35.19\/setup_galaxy_2.0 .35.19a.exe

But it gives me an 404 error, what am I doing wrong? Thank you in advance!

It's not necessary to escape the "/" characters in the URL. Try again without escaping them.

Thank you very much for your answer but still 404. Could you please write down exactly the address for this version (2.0.35.19a) and I will understand from now and on what to do. Thank you again for your patience!

Here's the link:

https://cdn.gog.com/open/galaxy/client/2.0.35.19/setup_galaxy_2.0.35.19a.exe

You are great Hustlefan! Thank you!

In Linux-land, escaping means - usually, but not always - to prefix with a \ character (other characters may be used depending on the specifics of the system in question). It's used to indicate that a character that would otherwise have a special purpose should be treated as a literal character.

For example, "/" is the separator between directories and filenames. "\/" means the literal character "/" without any special purpose.

So, removing all the escape sequences - all the "\" characters - leaves "https://content-system.gog.com/open_link/download?path=/open/galaxy/client/2.0.35.19/setup_galaxy_2.0.35.19a.exe" which is the URL for the installer.

And now there's a new version out - 2.0.37 beta - and the .json file in my earlier post - https://www.gog.com/forum/general_beta_gog_galaxy_2.0/is_there_an_offline_installer_for_galaxy_20/post8 - has been duly updated with the new installer's direct download URL.
