How to fix
Steam integration on GOG Galaxy not working
on Windows

Hi. I often use GOG Galaxy - I like to see all my games in one spot. However, for a few days now, Steam integration in GOG is not working, making it not show a huge portion of my games. Any idea how to fix this? I tried reconnecting, but it disconnected again.

GOG Galaxy enables gamers to combine their game libraries from numerous platforms into a single interface, improving the user experience by offering a centralized access point for all owned games. However, a common problem with Steam integration is that people may be unable to link their Steam account to GOG Galaxy.

In other cases, Steam integration simply disconnects, and users are unable to return it. This restriction frequently causes the inability to integrate their Steam library, restricting access to games from within the GOG Galaxy interface.

This type of problem can occur for a variety of causes, including network connectivity issues, out-of-date GOG Galaxy software, or issues with Steam's API that temporarily limit integration possibilities. Furthermore, security settings or firewall safeguards on the user's PC may prevent a connection between GOG Galaxy and Steam, complicating the integration procedure. Most commonly though, the issue lies with an outdated integration code, which remains not fixed.

To address this issue, both GOG Galaxy and Steam must be upgraded to the latest versions. Verifying network settings and modifying firewall or antivirus permissions may also be required to allow GOG Galaxy to communicate with Steam servers. Fixing the integration code also helped numerous users.

For those encountering persistent issues on their PCs, employing a PC repair tool [d1] can be an effective approach. This type of software is designed to automatically identify and fix underlying Windows issues that may be contributing to the problem, streamlining the troubleshooting process and potentially restoring the functionality of the integration feature.

Fix 1. Download the community-integrated code from GitHub

The community-integrated code can help address issues with Steam integration by providing updated integration scripts. These scripts are often developed by the community to solve common problems before official updates are released. Unfortunately, it is unlikely that CDPR will ever release an official update due to copyright and other legal issues. Thus, an unofficial fix is the only way to go.

• Make sure GOG Galaxy is fully closed.
• Open your browser and go to the download page.
• Download windows.zip from the list.
• Open File Explorer and navigate to the following location:
  %localappdata%\GOG.com\Galaxy\plugins\installed\steam_ca27391f-2675-49b1-92c0-896d43afa4f8
• If it does not exist, create it and name it steam_ca27391f-2675-49b1-92c0-896d43afa4f8. If it does exist, please remove all the contents from it.
• Place windows.zip into the folder, right-click, and select Extract.
• Launch GOG and check if the issue is gone.

Fix 2. Update GOG and Steam

Ensuring that both GOG Galaxy and Steam are running on their latest versions is crucial for compatibility and performance. Developers frequently release updates to fix bugs and improve functionality, which can resolve integration issues.

Steam

• Open the Steam client.
• Click on Steam in the upper left corner of the window.
• Select Check for Steam Client Updates.
• If an update is available, follow the prompts to install it.
• Restart Steam after the update is complete.

GOG Galaxy

• Open GOG Galaxy.
• Click on the cogwheel (Settings) at the top left corner.
• Select Check for updates.
• Wait till they are installed and reboot your PC.

Fix 3. Run network troubleshooter

Windows includes a network troubleshooting tool that can identify and resolve issues affecting your internet connection. Running this troubleshooter can eliminate network-related problems that might prevent GOG Galaxy from connecting to Steam.

Windows 11

• Type Troubleshoot in Windows search and press Enter.
• Select Other troubleshooters.
• Find Network & Internet troubleshooter from the list and select Run.
• Wait till the process is finished and apply the offered fixes.
• Restart your device.

Windows 10

• Right-click on Start and pick Settings.
• Go to the Network & Internet section.
• On the right side, find the Advanced network settings section.
• Click Network troubleshooter and wait.
• The fixes will be automatically applied.

Fix 4. Reset winsock

Resetting Winsock can resolve issues with internet connectivity by restoring the network settings to their default state. This can be particularly effective if the integration problem is caused by socket errors or network configuration issues.

• Type cmd in Windows search.
• Right-click on Command Prompt and select Run as administrator.
• Click Yes when UAC asks for permission.
• Type in the following command and press Enter:
  netsh winsock reset
• Reboot your PC and see whether it fixed Steam integration on GOG.

Fix 5. Allow GOG and Steam through Firewall

The Windows Firewall can block applications from accessing the internet, which may prevent GOG Galaxy and Steam from communicating. Configuring the firewall to allow both applications can resolve integration issues.

• Type in Control Panel in Windows search and press Enter.
• Go to System and Security and click on Windows Defender Firewall.
• On the left side of the window, click Allow an app or feature through Windows Defender Firewall.
• Click Change settings (if you are not on an administrator account, you will be asked to enter a password).
• Scroll down and enable Private and Public access to the following entries:
  Steam
  Steam Web Helper
  GalaxyClient Helper application
  GalaxyClientSertvice
  GOG Galaxy
• If it is missing from the list, click Allow another app and find GOG, then add it.
• Click OK.

Fix 6. Reinstall GOG

Having a fresh install of GOG Galaxy might resolve the issue automatically.

• Type Control Panel in Windows search and press Enter.
• Go to Programs > Uninstall a program.
• From the list, locate GOG Galaxy.
• Right-click and select Uninstall, then follow the prompts to finish the process.
• Restart your PC and reinstall the app from the official website.
