Verifying Cyberpunk 2077 Game File Integrity Without Steam

The methods for verifying the integrity of your Cyberpunk 2077 game files without using Steam depend on which platform you originally purchased and downloaded the game from. If you purchased the game on GOG (Good Old Games), you can use the GOG Galaxy client. If you’re using the Epic Games Launcher, the process is different again. This guide will walk you through each scenario, ensuring your game runs smoothly and is free of corrupted files.

Verifying Integrity on GOG Galaxy

If you purchased Cyberpunk 2077 through GOG, the GOG Galaxy launcher provides a built-in function to verify and repair your game files. This is the simplest and most direct method for GOG users.

Steps to Verify Integrity on GOG Galaxy:

Launch GOG Galaxy: Open the GOG Galaxy application on your computer. Make sure you are logged in with the GOG account you used to purchase Cyberpunk 2077.
Select Cyberpunk 2077: In the GOG Galaxy interface, navigate to your game library. Find Cyberpunk 2077 in your list of installed games.
Access Manage Installation Options: Click on Cyberpunk 2077 in your library. Look for a “Customize” button, typically located to the right of the “Play” button. Click this button to reveal a dropdown menu.
Verify / Repair: From the dropdown menu, select “Manage installation” and then choose the “Verify / Repair” option.
Wait for Verification: The GOG Galaxy client will now begin verifying the integrity of your game files. This process may take a while, depending on the size of the game and the speed of your storage device.
Address Any Issues: If any corrupted or missing files are detected during the verification process, the GOG Galaxy client will automatically download and replace them. Once the process is complete, you can launch Cyberpunk 2077.

Verifying Integrity on Epic Games Launcher

If you purchased Cyberpunk 2077 via the Epic Games Store, the Epic Games Launcher also offers a way to verify the integrity of the game files. The process is relatively straightforward.

Steps to Verify Integrity on Epic Games Launcher:

Open Epic Games Launcher: Launch the Epic Games Launcher on your computer. Ensure you’re logged in with the account you used to purchase Cyberpunk 2077.
Locate Cyberpunk 2077: In the Epic Games Launcher, go to your game library. Find Cyberpunk 2077 in your list of installed games.
Access the Manage Menu: Click on the three dots (ellipsis) located to the right of the Cyberpunk 2077 game listing. This will open a context menu.
Select Manage: In the context menu, select the “Manage” option.
Click Verify: In the Manage section, you will see a “Verify” button. Click this button to initiate the file verification process.
Wait for Verification: The Epic Games Launcher will begin verifying the integrity of your Cyberpunk 2077 game files. As with GOG Galaxy, this process may take some time to complete.
Address Any Issues: If any corrupted or missing files are found, the Epic Games Launcher will automatically download and replace them. After the verification is complete, you can launch Cyberpunk 2077.

Manual File Verification (Advanced)

In some cases, the launchers may not fully resolve issues, or you might want to manually verify files for more granular control. This process is more technical but can be useful for pinpointing specific problem areas.

Steps to Manually Verify Files:

Locate Game Installation Folder: Find the Cyberpunk 2077 installation directory on your computer. This is typically located in a folder like C:Program Files (x86)GOG GalaxyGamesCyberpunk 2077 (for GOG) or C:Program FilesEpic GamesCyberpunk2077 (for Epic).
Identify Key Files: Research the key files and directories that Cyberpunk 2077 requires to run correctly. This can involve consulting online forums, the game’s official website, or community resources.
Compare File Sizes and Dates: Manually compare the file sizes and modification dates of the files in your installation folder with known good versions (if available). This method is best used if you suspect a recent file corruption.
Use Checksum Tools: Use a checksum tool (like MD5, SHA-1, or SHA-256) to generate checksums of your game files. Compare these checksums with known good checksums. If the checksums don’t match, the file is likely corrupted.
- FCIV (File Checksum Integrity Verifier): One commonly used tool is Microsoft’s FCIV.
Replace or Reinstall Corrupted Files: If you identify corrupted files, replace them with known good versions (if you have them) or consider reinstalling the game to ensure all files are correct.

Additional Troubleshooting Tips

Restart Your Computer: After verifying and repairing your game files, restart your computer to ensure that all changes are properly applied.
Check Your Internet Connection: Ensure you have a stable and reliable internet connection during the verification and repair process.
Update Graphics Drivers: Make sure your graphics drivers are up to date. Outdated drivers can cause various issues with game performance and stability.
Disable Antivirus Software: Temporarily disable your antivirus software during the verification and repair process. Sometimes, antivirus programs can interfere with game files.
Run as Administrator: Run the game launcher (GOG Galaxy or Epic Games Launcher) as an administrator. This can help prevent permission issues that might interfere with the verification process.
Reinstall the Game: As a last resort, consider reinstalling Cyberpunk 2077. This ensures that all game files are downloaded and installed correctly.
