How to Install & Play GOG Games on Windows

GOG.com sells DRM-free PC games, which means once you download a game, you can install and play it without any online activation or launcher running in the background. This guide walks you through the two main ways to get GOG games running on Windows: using the optional GOG GALAXY client for convenience, or downloading offline installers directly from the website. You’ll need a GOG account, a Windows PC (Windows 10 or 11 recommended), and enough free disk space for the game you want.

What You’ll Need

• A GOG account (free to create at gog.com)
• A purchased game (or a free game from your library)
• Windows 10 or 11 (older versions may work but aren’t officially supported)
• Stable internet connection for downloading
• Sufficient free storage space (check the game’s store page for requirements)

Step-by-Step

Method 1: Using GOG GALAXY (Recommended for convenience)

1. Download GOG GALAXY: Go to gog.com/galaxy and click the “Download GOG GALAXY” button. Save the installer to your PC.
2. Install GOG GALAXY: Run the downloaded setup file. Follow the on-screen prompts—choose your installation folder and click “Install.” Once done, launch GALAXY.
3. Log in: Enter your GOG email and password. If you have two-factor authentication enabled, enter the code sent to your device.
4. Find your game: Click the “Owned” tab on the left sidebar. You’ll see all games linked to your account. If the game isn’t there, click the refresh icon or check your library filters.
5. Install the game: Click the game’s tile to open its page, then click the “Install” button (usually green). Choose a folder (default is C:\GOG Games) and click “Install.” GALAXY will download and install the game automatically.
6. Play: Once installation finishes, the button changes to “Play.” Click it to launch the game. GALAXY doesn’t need to stay open after the game starts—you can close it and the game will still run.

Method 2: Using Offline Installers (No client needed)

1. Go to your library: Log in to gog.com in a web browser, hover over your username, and click “Library.”
2. Open the game page: Click on the game you want to install.
3. Download offline installers: Scroll down to “Offline Backup Game Installers.” Click the download link for the main installer (usually the largest file, often named “setup_game_name_version.exe”). If the game has multiple parts (e.g., .bin files), download all of them into the same folder.
4. Run the installer: Double-click the downloaded .exe file. Windows may show a SmartScreen warning—click “More info” then “Run anyway” if you trust the file.
5. Follow the wizard: Choose your language, accept the license, and select an installation folder. The installer will extract files and may prompt you for additional .bin files if they’re in the same folder.
6. Launch the game: After installation, a shortcut is added to your Start Menu and desktop. Double-click the shortcut to play. No GOG account or internet connection is required after installation.

Common Mistakes

• Downloading only part 1 of a multi-part installer: If a game has multiple .bin files, you must download all of them. Missing any part causes the installer to fail or ask for a file you don’t have.
• Installing to Program Files: Windows often restricts write access to C:\Program Files, which can cause save issues or permission errors. Use the default C:\GOG Games or a folder you created.
• Running as administrator unnecessarily: If you install to a normal folder, you don’t need admin rights. Running as admin can sometimes cause game mods or overlays to behave oddly.
• Deleting installer files after installation: Offline installers are your backup. If you delete them and need to reinstall, you’ll have to re-download.
• Ignoring system requirements: Some GOG games are older and may need compatibility settings (right-click the .exe → Properties → Compatibility tab) to run on modern Windows.

Tips

• Use GALAXY for updates: GOG GALAXY automatically checks for patches and DLC. If you use offline installers, you must manually check the game’s page for updates.
• Back up offline installers: Store them on an external drive or cloud service. This is the biggest advantage of GOG—you can reinstall without re-downloading.
• Enable cloud saves: In GALAXY, right-click the game → “Manage Installation” → “Configure” → enable “Cloud Saves.” This syncs your saves across PCs.
• Check for free games: GOG frequently gives away free games (like classic RPGs). Claim them—they stay in your library forever.
• Use the GOG GALAXY overlay: Press Shift+Tab in-game to open the overlay for screenshots, friends chat, and time tracking. You can disable it in settings if it causes issues.

Troubleshooting

• Installer says “File not found” for .bin files: Make sure all .bin files are in the same folder as the .exe. If they are, try re-downloading the missing part—it may be corrupted.
• Game won’t start, or crashes on launch: Right-click the game in GALAXY → “Manage Installation” → “Verify/Repair.” This checks file integrity. For offline installs, reinstall or try running in compatibility mode (Windows 7 or XP).
• GALAXY won’t log in: Check your internet connection, disable VPN or proxy, and try again. If you use two-factor authentication, ensure your device’s time is correct.
• Game runs slowly or stutters: Update your graphics drivers. Also, close background apps like browsers or overlays (Discord, GeForce Experience) that may conflict.
• Missing DLL or DirectX errors: GOG games often include redistributable folders (like _CommonRedist). Run the installers inside them (DirectX, Visual C++) to install required components.
• Game doesn’t appear in GALAXY library: Click the gear icon in GALAXY → “Settings” → “Game Features” → “Integrations” and ensure “GOG” is enabled. Also, refresh your library by pressing F5.

Frequently Asked Questions

Do I need GOG GALAXY to play GOG games?

No. GALAXY is optional. You can download offline installers from your library and play without any client. GALAXY just adds convenience (auto-updates, cloud saves, friends).

Can I install a GOG game on multiple computers?

Yes. You can download and install the same game on as many PCs as you like. There’s no activation limit. However, some multiplayer features may require a separate account for online services.

Can I play GOG games without an internet connection?

Yes, for single-player games. Once installed, they run completely offline. Multiplayer modes may require internet and additional accounts (like for online matchmaking).

How do I update a game installed via offline installer?

Check the game’s page on GOG for patch notes. Download the latest patch installer and run it over your existing installation. Or, install GALAXY and it will handle updates automatically.

Can I transfer my GOG games to another PC without re-downloading?

Yes. Copy the game’s installation folder (e.g., C:\GOG Games\GameName) to a USB drive or network location, then paste it to the same path on the new PC. You may need to run the game’s .exe directly; if it fails, run the offline installer to fix registry entries.

Are GOG games DRM-free?

Yes, that’s GOG’s core promise. You can copy, back up, and install your games without any online verification. Some multiplayer games may include third-party DRM for online services, but the single-player portion is DRM-free.
