Steam 1 File Failed To Validate And Will Be Reacquired

Steam, despite being the most popular and used game distribution platform for games such as Terraria, PUBG, and Minecraft, has certain issues. For example, some users have reported the error of Steam 1 file failed to validate and will be reacquired while launching a game. 

This usually occurs when you download a game and some of its files are corrupted or damaged. You might not be able to launch the game at all. 

If you are among these users facing such an issue, you are in the right place. Here we will help you out in addressing this issue of yours. 

What Does the Steam 1 File Failed to Validate and Will Be Reacquired error mean?

Steam is an important part of checking the integrity of the game. Usually, when you download the game from steam, not all the files might not be downloaded. This might happen due to server issues. 

This will create hindrances while or after launching the game, or it might not work at all due to the presence of bugs. Hence users need to verify the integrity of the game files. 

Steam is responsible for matching the files of the game you have downloaded with the ones uploaded on their servers. All the missing or corrupted files of the games will be downloaded again.

But in a few cases, you might encounter the 1 file failed to validate and will be required error. This means that 1 or more files are unsuccessful in validating. Several reasons can be behind this error, such as:

  • Mods are responsible most of the time for preventing the steam games from getting the validation.
  • Due to memory corruption.
  • The presence of third-party services thus prevents the validation process.
  • Some controllers can also cause this error.
  • You didn’t clean boot Windows. 
  • Due to Windows Firewall settings.
  • Because the downloaded game is corrupt, hence is not validating.

In several cases, the modes installed for a game conflict with the steam client and lead to errors like the one you are facing now. Verifying the game is responsible for checking the manifest of the game you have downloaded with the steam servers. 

Files present on your system are listed in the manifest. And the manifest present on the steam servers has the list containing all the files that should be there as per the most recent update. 

When both lists don’t match, you’ll see the error on the screen because some files might fail to validate. The files should be either removed or replaced. And if this is not the case, try running the verification check again.

But still, this error appears on the screen, and mods on your device tamper with the performance. Hence disable all the mods, and restart Steam. After this, check the error. 

Note: You can also verify integrity of game files. 

Open The Game From Its Main Game Folder

You can also use the installation folder directly to open the game you are playing. As all the games you have installed are independent applications. All of them have their executable presence in the local files. You can try running from these. 

  • Open the Steam Directory.
  • Go to this folder: Steamapps<common
  • Select the game with which you are facing the issues, from the list of all the installed games on your device. 
  • Open the folder named Game.
  • Open the folder named bin.
  • If you have a 32-bit configuration open win32, or if you have a 64-bit configuration open win64.
  • Right-click on the game’s main launcher.
  • Click on the option to Run As Administrator.

Check For Bad Sectors

Check For Bad Sectors

It has been observed that bad sectors in the hard drives are responsible for the error. Due to some permanent damage, this sector is unwritable or inaccessible. Permanent damage, in most cases, is the physical damage caused to the hard drives. Bad sectors can be searched by running the utility of chkdsk. Microsoft develops this utility. 

If it finds any bad sectors on your drive, these sectors are flagged as unusable. Along with it, the operating system will always skip the bad sectors in the future. You might be experiencing this error as the game you installed is in a drive with bad sectors. 

Check disk is the full form of Chkdsk. It will use all the resources available to correct the errors present after finding them. Particularly if you cannot pinpoint the error, this will contribute to troubleshooting for errors. This command can be run in two ways, they are:

Using File Explorer

  • Open the File Explorer.
  • Go to This PC on the left corner of your screen.
  • Right-click on the hard drive you want to check.
  • Select Properties in the drop-down menu.
  • Select the Tools to tab at the top of the new window.
  • Click on the button named, and check under the column of Error Checking.

Wait for the chkdsk to run without interrupting in between.

Using the Command Prompt

Run window
  • Type cmd
Run tool with the CMD command
  • Write CHKDSK C: in the command prompt. You can check any drive by replacing the C with the drive’s name.
run chkdsk

End All Steam Processes

End All Steam Processes

Downloaded steam and any update install might cause the issue. You need to restart the client properly after every update. Otherwise, there can be an incorrect configuration with your client. 

Do this:

  • Launch the Run application by pressing Windows + R keys.
  • Type taskmgr in the dialogue box and open Task Manager.
Taskmgr

Disconnect Your Controller And Other Related Software

Disconnect Your Controller And Other Related Software

This issue can also be triggered if your controllers are connected to the PC. Except for the keyboard or standard mouse, these controllers can be anything such as a joystick, mouse, controller pads, etc. you should disable all of these devices. And with the help of the task manager, stop these controllers’ dedicated software from running and restart the steam.

There is no secret that steam conflicts with the windows firewall. Steam downloads the games and updates in the background, even if you are using windows for some other purpose. 

With this, you don’t have to wait for the installation process to be completed to use the device for playing games or even using the steam client. Steam ensures you get the best experience for gaming as it has access to several system configurations. 

Rarely but sometimes windows firewalls block steam as it marls few processes of it as malicious. This isn’t easy to pinpoint as you won’t be aware of this happening in the background. 

You can always try disabling the firewall temporarily and see if that fixes the error you are facing. Along with this, the antivirus can also block the actions of steams, as it might consider them a threat. The obvious solution, in this case, is to uninstall the antivirus, which might not be beneficial in long term. 

Your device will be exposed to numerous threats after uninstalling the antivirus. Hence we will always recommend you add steam in the exception scanning. Hence steam will be treated as it does not exist by the antivirus. 

Delete The cfg File (Configuration File)

Delete The cfg File (Configuration File)

Possibly, the configuration of your game’s file is corrupted, and it is impossible to replace it. Hence the error is shown; this can be the same file pointed to by the streams client. In this case, you should try deleting that config file and launching steam again. Then verify the integrity of the game.

Once you delete the configuration file, steam will replace it with a new copy from its server. 

  • Go to the Steam Directory.
  • Open the userdata folder.
  • Select your steam ID and click it.
  • Delete all the folders in the directory.
  • Relaunch the steam.

Delete The Local File Content

You can also try deleting all the content of the local file of the game if you are facing the error. And then start the download again. But before moving forward with this fix, ensure you have enabled steam cloud. This won’t lead to deleting progress or achievements but only the installation data.

  • Open the Steam Client.
  • Select the Library tab on top.
  • Right-click on the game with which you are facing the error.
  • Click on Properties in the list of options.
  • Go to the Local Files Tab.
  • Click on the Browse Local Files button.
  • Delete everything in the game’s local files folder.
  • Before you launch it again, stop all the steam services and processes.

There are two possibilities: first, Steam will download the game file you have deleted in the previous steps, or second, the game will be removed from the library. You can go to the steam store and download the files again if this is the case. After all, this, launch the game and check if the error is finally fixed.

Run A CHKDSK Scan

Run A CHKDSK Scan

To run a CHKDSK scan do this:

  • Open the File Explorer.
  • Go to This PC on the left corner of your screen. 
  • Right-click on the hard drive you want to check.
  • Select Properties in the drop-down menu.
  • Select the Tools to tab on the top of the new window.
  • Click on the button named, check.
  • Click on the Scan Drive option even if the window, stating no scan is required appears on the screen.

Refresh Your Steam Files

This is the last fix if nothing so far has worked for you. You can try reinstalling steam and check if that fixes the error. Don’t worry while refreshing the steam files, everything will be preserved (downloaded games), so you don’t have to make an effort to download them again.

This fix will delete the configured files of the steam client, and installation will forcefully take place. Hence any corrupted or damaged files will be replaced automatically. But you need to log in again with the help of your credentials. And hence if you don’t have them, then do not proceed with this fix. 

You should wait for the process to be completed, even if it takes a little longer.
