Download Fortect here! One of our readers told us that after the game crashes, he uses the game integrity file verification but he gets the message 1 file failed to validate and will be reacquired every time. Thus, the Verify Integrity of Game Files option doesn’t fix the game crashing when that error message pops up.

What does it mean when 1 file failed to validate and will be reacquired?

During the game integrity verification, Steam compares all the files from your installed game to the one on the server. The error thus means that during this verification, one of the files was not on par with the original one and fails the verification.

Why are my Steam files not validating?

There are various reasons why the Steam game files fail to validate, including file corruption, bad sectors on your drive, accidental renaming of files, and more. And this error goes further than not validating 1 file. Users reported the error occurring as 2,3,4,18,33 files failed to validate and will be reacquired. Moreover, there are multiple games in which this error occurs such as:

CSGO Skyrim Elden Ring Fallout: New Vegas, Terraria Warfare 2 (MW2) Ark

Also, the 1 file failed to validate and will be reacquired error was encountered in many games such as CSGO, Skyrim, Elden Ring, Fallout: New Vegas, Terraria, and others. There isn’t any specific guaranteed fix for that error, but these resolutions might fix it.

What to do if Steam says 1 file failed to validate and will be reacquired?

1. Run a CHKDSK Scan

The Steam failed to validate and will be reacquired error can be due to bad drive sectors. Some Steam users have confirmed that, and the Check Disk (CHKDSK) utility can repair drive sectors to fix the Steam failed to validate error.

2. Turn Off Windows Defender Firewall

The Windows Defender Firewall can and does conflict with Steam for some users. Thus, Steam’s failure to validate error can be due to firewall blocks.

3. Perform a Clean Boot

The next guided solution show you the correct method to perform a clean boot to fix the Steam error Files failed to validate and will be reacquired.

  1. Press the Windows key + R to start Run, type msconfig, and press Enter or click OK.

  2. On the General tab, select the Selective startup option, then uncheck Load startup items and check Load system services and Use original boot configuration.

  3. Now, go to the Services tab and select the Hide all Microsoft services option.

  4. Click Disable all to deselect the third-party services.

  5. Press the Apply and OK buttons, then click the Restart button on the dialog box window that opens.

If the clean boot fixes the issue, users should leave third-party antivirus utilities or system optimization software out of the system startup. Alternatively, you can add Steam to antivirus utilities’ exception lists instead.

4. Reinstall Steam and scan the Registry

The registry cleaner will erase leftover registry entries after removing Steam. Those are some of the resolutions that will help you fix the Steam failed to validate error. In addition, you can also try bypassing the Steam client by launching the game (which usually crashes) from the Steamapps common folder. The game launcher will be in a win32 or win64 subfolder within the game’s folder. You might also be interested in our guide including the best ways to fix verify integrity of game files not working.
