How to Fix Steam Content File Locked Error When Launching Games

06/14/2019     Author: Billy Gray

A common error on Steam is the content file locked error message. This appears when Steam can’t read the games on your disk. There can be a number of reasons for this. If this message is showing, then you cannot launch your game until it’s been solved.

The ultimate solution is to uninstall all the games that are showing this message, then uninstall Steam, reinstall it and reinstall all the games and try again. Obviously, this takes a lot of time and might result in you losing your game data as well. There are much simpler options than this.

In this post, we’ll take a look at several ways of fixing this Steam game error.

FIX I: Get your antivirus in check

Sometimes your antivirus will interfere with the launching of your Steam games. This is because it might think that the games are malware and thus will refuse to load them. Don’t worry, your games are most likely not hosting malware (although, you never know). Either way, the first thing you should is run a full scan on your computer to make sure that there aren’t any threats lurking in the woodwork.

Once you’ve established that your PC is free from viruses, you can turn off your antivirus or exempt the particular games from it. Some antivirus software, such as McAfee, don’t allow you to exempt specific files from being scanned. In this case, you’ll have to turn off real time scanning while you verify the integrity of the game.

For McAfee:

  1. Open McAfee.
  2. Go to Virus and Spyware Protection.
  3. Turn off Real Time Scanning.

For Kaspersky AV:

  1. Open Kaspersky AV.
  2. Go to Threads and Exclusions.
  3. Mark Steam.exe as a trusted application.


  1. Go to your Steam directory file: C: / Program File / Steam / SteamApps / Common.
  2. Copy the address.
  3. Open ESET NOD32.
  4. Paste Steam directory address in Exclude from real time scanning.


Once you’ve excluded Steam from your antivirus software’s real time scanning, you’ll want to locate all the games that have the Content File Blocked error message when you attempt to launch them. You’ll need to restart your computer first so you can fully re-launch Steam.

  1. Find the game that’s playing up.
  2. Right click and select
  3. Go to the Local Files
  4. Click Verify integrity of game cache…
  5. This will take a while. Wait for it to finish verifying.

This should solve the problem. If it doesn’t, then you’ll have to try one of these other methods.

FIX II: Repair corrupt files

If the above method didn’t work, then it’s likely that some of the game files have gone missing or have become corrupt. There’s a simple way to troubleshoot what’s wrong and fix it without causing a vein to pop out of the side of your head.

  • First, go to your Steam directory. You can go to C: / Program Files (x86) / Steam.
  • Open the Logs folder, then open txt.
  • Go to the bottom of the text file. This is where you’ll see any recent errors.

  • Once you can see the errors, take note of the AppID number. In this error, it’s 346110. You want to pay attention to the second number which is the ID of the mod file. In this case, it’s 570371714.
  • Go to the root folder. It will be the same name as the second number (570371714).
  • Fix the issue here.
  • Restart Steam and go to downloads – it will be asking you to download an update for the game. Do this and it should work afterwards.

The nuclear option……….

If none of the above methods work, then you might want to consider the big bomb. That’s right – delete the games and Steam and reinstall all of it from scratch. This is a pretty tedious process as it takes ages and seems unnecessary.

But then, if nothing else is working, it might be your only option. Good luck!
