How to fix Steam 1 file failed to validate and will be reacquired

Steam is a good game circulation platform but as a desktop app, it takes the grunt work out of installing games on a system. All you have to do is click on the Install button after purchasing a game and Steam will take care of everything. Once installed, Steam also takes care of game updates and users have little to worry about but possibly a game restart.

The Steam 1 file has not been verified and will be rediscovered

Seam: 1 file failed and will be rediscovered

Game installation and updates on Steam are handled mostly in the background. Steam update when you open the app, and will install updates for games before opening the game. If a game is updating, you will not be able to play it until the update is applied. That said, if the game is updated and you get the ‘1 file failed to confirm and it will be restored’ when you try to play it, it means there is a problem with the game files.

1. Verify game files

This is the first configuration that you should try if we find the Steam 1 file that it did not verify and a redirection error will be made either when it opens Steam or opens a particular game on Steam.

  1. Open Steam and go to the Library.
  2. Right-click on the game you want to play and select Properties from the context menu.
  3. Go to the Files tab.
  4. ClickVerify file integrity.
  5. Allow Steam to view files and download new ones if needed.
  6. Steam restart.

2. Run a disk scan

Check the disk on which you store your Steam games / library for errors. The problem may be due to disk errors and not Steam.

  1. Open File Explorer.
  2. Go for this PC.
  3. Right-click the driver with your Steam library and select Properties.
  4. Go to the Tools tab.
  5. Click Check and let the full scan run.

3. Disable mods

Game mods can be game changers for many games but can cause problems, especially if they are not compatible with game updates. Try disabling the game modes you have installed and Steam will start working.

On that note, if you have installed game-changing apps that add cheats, or that could be described as a cheat device, uninstall it. Steam also detects and blocks such app and the app may not work.

4. Steam reset

Steam updates frequently and the upgrades are usually successful. That said, an update that may have run into problems when it installs may indicate that the Steam 1 file was not verified and a redirection error will be made. It is best to uninstall and reinstall Steam (this will not erase game data).

  1. Open Control Panel.
  2. Go to Programs> Install Program.
  3. Select Steam and click the Uninstall button.
  4. Restart the system.
  5. Download and reinstall Steam.

5. Remove controllers

Regulators, especially unofficial regulators, can sometimes cause problems with Steam. If you have a controller connected to your system, disconnect and open Steam. If Steam opens without any problem, delete the third-party administrator profiles / configurations you added and uninstall and reinstall the controller.

You can uninstall an administrator from Device Manager. Look for it under Bluetooth devices if it is a Bluetooth controller or under USB devices if it is a wireless controller. Reinstall the controller and it should work.


Steam is not capable of problems but most of its problems are easily solved. More importantly, it is rare for difficulties from one game to affect another. That said, make sure your games are always backed up. Take a regular backup in case you need to rebuild your local library and game files.
