The advent of digital game distribution platforms, like Steam, has revolutionized the way we consume video games.

Additionally, it conveniently handles game updates, freeing users from the otherwise daunting task of manual updates. However, despite the convenience, Steam is not without its quirks and occasional hitches. In this blog post, we’re going to tackle one such error – the “1 file failed to validate and will be reacquired” message.

It’s a relatively common issue, often appearing when you’re trying to launch a game. This error can be incredibly frustrating, particularly when you’re all set for a gaming session. But fret not! This error message is not a death sentence for your gaming aspirations. Quite the contrary, it’s typically a relatively easy problem to fix. So, buckle up as we take you through the step-by-step process to resolve this issue and get you back into your gaming session in no time.

Understanding the Issue

Before we dive into the fixes, let’s take a moment to understand what this message implies. Primarily, the “1 file failed to validate and will be reacquired” error is indicative of an issue with the game files. This could be due to a variety of factors, but most commonly, it’s related to either corrupted game files or issues with game mods. Luckily, we have a handful of strategies to mitigate these issues.

Solution 1: Validate Game Files

One of the first things you can do when faced with this error is to validate your game files. This process is straightforward and is carried out within the Steam client.

  1. Start your Steam client.

    Click on the Steam icon on your desktop or in your computer’s taskbar to open Steam.

  2. Go to your Library.

    On the top menu, find and click on “Library” to view your collection of games.

  3. Find the game that’s causing issues.

    Scroll through your Library or use the search bar to find the game that’s having problems.

  4. Access the game’s Properties.

    Right-click on the game title in your library, then select “Properties” from the context menu that appears.

  5. Navigate to the Local Files tab.

    In the Properties window that opens, find and click on the “Local Files” tab located at the top of the window.

  6. Verify the integrity of the game files.

    Within the Local Files tab, look for the button that says “Verify Integrity of Game Files” and click on it.

  7. Allow Steam to check and download files.

    Steam will now scan all of the game’s files to ensure they’re correct and complete. If it finds any files that are missing or corrupted, it will automatically download and replace them.

  8. Restart Steam.

    Once the verification process is complete, close and restart Steam. This will ensure that all new files are properly integrated and your game should now work as intended.

Solution 2: Run a Disk Check

If validating the game files doesn’t resolve the issue, you might want to consider checking your disk for errors. It’s possible that disk errors might be the culprit rather than an issue with Steam.

  1. Open File Explorer and navigate to This PC.
  2. Right-click the drive containing your Steam library and select Properties.
  3. In the Properties window, go to the Tools tab.
  4. Click Check and allow the disk check to run its course.

Solution 3: Reinstall Steam

Another possible solution is reinstalling Steam. While Steam updates are usually successful, they can occasionally run into issues. In such cases, uninstalling and reinstalling Steam might be necessary.

  1. Open the Control Panel and navigate to Programs > Uninstall a program.
  2. Select Steam and click the Uninstall button.
  3. Restart your system.
  4. Download and install Steam again.

Solution 4: Turn off the Game Mods

Mods can breathe new life into a game, but they can also cause compatibility issues, especially following game updates. If you’re using any mods with your game, consider disabling them temporarily to see if that resolves the issue. Likewise, if you have any apps installed that modify a game or add cheats, uninstall them as Steam might be flagging them as problematic.

Solution 5: Disconnect Controllers

Certain unofficial controllers connected to your system can occasionally cause issues with Steam. Try disconnecting any controllers, opening Steam, and seeing if the issue persists. If this seems to solve the problem, consider uninstalling and reinstalling the controller.
