Anti Cheat Integrity Check Failed Squad | Fix In Minutes

Guide / By

The “anti cheat integrity check failed” Squad error means Easy Anti-Cheat can’t verify a file or service on your PC, so a repair plus a file check often clears it.

You click Join, the map loads, then you’re kicked with an integrity check message. It feels random, but it usually comes from a corrupted game file, an Easy Anti-Cheat service that didn’t install cleanly, a cache that went bad, or a background app that EAC dislikes.

If you’re seeing anti cheat integrity check failed squad on every server, don’t shotgun ten fixes at once. Work through a clean order. You’ll know what changed, and you’ll avoid breaking a working setup.

What This Error In Squad Is Really Checking

Squad uses Easy Anti-Cheat (EAC) to confirm that the game’s files and the anti-cheat service match what the server expects. When the check fails, the server disconnects you. That’s why you might launch the game fine yet still get booted when you try to enter a match.

The check happens right around the server handshake, so anything that blocks EAC from starting cleanly can trigger it. It also checks file versions, so a single missing or damaged file can be enough.

If you see a code like 0x2200, treat it as a broad integrity failure bucket, not one single cause. The job is to make your install, your EAC layer, and your cached settings line up again.

Common Trigger What You Notice First Move
Corrupted Squad file Kicked on join, every server Verify files in Steam
EAC install glitch Starts after patch or reinstall Uninstall then install EAC
Bad cache or config Started after settings changes Clear cached user data
Security block Works once, then fails again Allow Squad and EAC
Network stack issue Other games feel unstable Reset Winsock, flush DNS

Fast Checks Before You Change Anything Big

Do these first. They’re quick, they’re safe, and they catch the stuff that can waste an hour.

  • Reboot The PC — A full reboot clears stuck services and stale hooks that a game restart won’t reset.
  • Close Overlay Apps — Quit overlay recorders, RGB tools, performance tuners, and “game booster” apps, then try again.
  • Run Steam As Admin — Launch Steam with admin rights once, then start Squad from Steam.
  • Sync Windows Time — Make sure time zone is right, then sync time and retry.
  • Unplug Extra USB Devices — Test with only keyboard and mouse to rule out odd HID drivers.

If one of these clears it, you’re done. If not, move on and repair the pieces that EAC checks most.

Anti Cheat Integrity Check Failed In Squad After Updates

If the error showed up right after a patch, treat it like a mismatch between what’s on your drive and what the servers expect. A partial download or one stale file can trip EAC during the join handshake.

Verify Squad Files In Steam

Steam can scan your install and re-download only what’s missing or damaged.

  1. Open Steam Library — Find Squad.
  2. Open Properties — Right-click Squad, then click Properties.
  3. Verify Installed Files — Go to Installed Files, then click Verify integrity of game files.
  4. Restart Steam — Close Steam fully, open it again, then test a server join.

Reinstall Easy Anti-Cheat From The Squad Folder

Offworld Industries recommends repairing or reinstalling EAC from your Squad directory. Run the installer as administrator, select Squad, uninstall EAC, then install it again.

  1. Browse Local Files — In Steam, right-click Squad, then Manage, then Browse local files.
  2. Open EasyAntiCheat Folder — Find the EasyAntiCheat directory.
  3. Run The Setup As Admin — Launch EasyAntiCheat_Setup.exe with admin rights.
  4. Uninstall Then Install — Select Squad, uninstall EAC, then install.

After this, verify files once more. That combo fixes a lot of “patch day” integrity failures.

Clear Cached User Data

If config or cache files are corrupted, EAC can still fail even when the core install is clean. Clear cache first from inside the game, then fall back to deleting the folder.

  • Use The In-Game Button — In Squad, go to Settings, then Game Settings, then click Clear Cached User Data.
  • Delete The AppData Folder — In Windows, open %LocalAppData% and delete the Squad folder.

Deleting the folder resets keybinds and video settings. Take a quick screenshot of your settings if you want to rebuild them faster.

Remove Workshop Mods And Leftover Mod Files

Outdated Steam Workshop mods can break launch, break joins, or leave behind files that confuse the game after an update. Offworld Industries recommends unsubscribing from all mods first, then deleting the Workshop content folder for Squad.

  1. Unsubscribe From All Mods — In Steam Workshop, open Your Files, then Subscribed Items, then Unsubscribe from all.
  2. Delete The Mod Folder — In your Steam library, delete workshop\content\393380.
  3. Restart Steam — Close Steam, open it again, then verify Squad files once.

When the base game is stable again, re-subscribe to mods one at a time. If the error returns right after you add one back, you’ve found your culprit.

Anti Cheat Integrity Check Failed Squad

If you keep seeing this message after verify, EAC reinstall, and cache clearing, focus on the EAC service itself. EAC runs as a Windows service while an EAC-protected game is running, and that service can get out of shape.

Epic’s Easy Anti-Cheat documentation describes a manual repair flow from an admin Command Prompt.

  1. Open Admin Command Prompt — Search Command Prompt, then Run as administrator.
  2. Change To The EAC Folder — Run: cd C:\Program Files (x86)\EasyAntiCheat_EOS
  3. Run Repair — Run: EasyAntiCheat_EOS.exe repair
  4. Confirm Success — Run: echo %ERRORLEVEL% and look for 0.

If that folder path isn’t on your PC, use the installer inside the Squad folder (the steps above) and test again. Avoid wiping the service unless you understand that EAC is shared by other games on the same PC.

Windows Fixes That Stop Integrity Failures From Coming Back

If EAC and Squad are healthy yet the kick keeps returning, the cause is often outside the game folder. Anti-cheat tools touch drivers, services, and security layers, so this section is about removing the common tripwires.

Check Security Quarantine And Allow The Game

Windows Security or a third-party antivirus can quarantine a file after a definition update. You might not notice until the next join attempt.

  • Review Protection History — In Windows Security, open Protection history and restore any Squad or EAC items that were removed.
  • Add Folder Exclusions — Add exclusions for the Squad install folder and its EasyAntiCheat folder, then reboot and test.
  • Test Firewall Rules — Allow Squad and EAC through Windows Firewall for private networks, then retry.

Check Install Drive And Permissions

EAC is picky about clean reads. External drives, flaky SSD firmware, and odd file permissions can produce a false “corrupt file” vibe.

  • Move To An Internal Drive — If Squad is on an external drive, install it on an internal SSD, then verify files.
  • Avoid Folder Encryption — Don’t place the game inside an encrypted or redirected folder that blocks service access.
  • Run One Test From A New Windows User — A fresh user profile can rule out broken permissions in your main profile.

Remove Cheat Tools And Memory Editors

Offworld Industries flags Cheat Engine as a known trigger. Even if you used it for a single-player title, leaving it installed can cause EAC to reject your session. Uninstall it, reboot, then test.

Turn Off Overlays And Injectors

Some overlays hook the render chain in a way that EAC hates. Test with overlays off: Steam overlay, Discord overlay, GPU overlays, and screen capture utilities.

Update Windows And GPU Drivers

Update Windows, then install the latest GPU driver from NVIDIA, AMD, or Intel, then reboot. If you updated drivers and the issue started right after, try a clean reinstall of the driver package and test again.

Try A Clean Boot Test

If you can’t tell which background app is involved, try a clean boot. Disable non-Microsoft startup items, reboot, then test one server join. If it works, turn items back on in small batches until the trigger shows itself.

Network Resets And Connection Checks

Not every integrity check failure is a file issue. EAC also relies on a clean network stack for its handshake. Offworld Industries lists two commands that reset common Windows networking glitches, followed by a reboot.

  1. Open Admin Command Prompt — Run Command Prompt as administrator.
  2. Reset Winsock — Run: netsh winsock reset
  3. Flush DNS — Run: ipconfig /flushdns
  4. Reboot And Retest — Restart the PC, then try joining again.

Turn off any VPN for this test. If you’re on Wi-Fi and the signal is weak, test once on Ethernet to rule out packet loss. Also sign out of Steam and sign back in, then retry, since a stale session can slow the join flow.

If your router has been on for months, reboot it too. Then test with a wired connection once, even if you plan to go back to Wi-Fi after.

When Nothing Works Yet

If you’ve worked through the steps above and still can’t join any server, stop guessing and collect clean details. A good report is the fastest way to get a real answer.

Find And Zip Your Squad Logs

Offworld Industries lists the log location under your Windows user profile. On PCs you’ll find it at C:\Users\YourUsername\AppData\Local\SquadGame. Zip the Saved folder so it stays in one piece.

  1. Open The Folder — Press Windows+R, type %LocalAppData%, then open the SquadGame folder.
  2. Zip The Saved Folder — Right-click Saved, then choose Send to, then Compressed (zipped) folder.
  3. Store A Copy — Put the zip on your desktop so it won’t be overwritten by a new launch.

Write down the full error text, including any code like 0x2200, and note whether it happens on every server or only on specific ones.

Do A Clean Reinstall If You Need It

If you decide to reinstall Squad, uninstall from Steam, then delete any leftover Squad folder in the install path before reinstalling. After reinstall, verify files once, run the EAC setup once, then test a join.

Check Linux Or Proton Setups

If you play on Linux through Proton, install Proton EasyAntiCheat Runtime in Steam and test with Proton Experimental. The same integrity failure can show up when the runtime isn’t lined up with the game’s EAC setup.

When you submit a request to Offworld Industries, attach your logs and list the steps you already tried. If the error pops up again after a patch, search your logs for anti cheat integrity check failed squad so you can jump straight to the right section next time.

One last caution: skip “launcher swap” tricks that tell you to copy executables between games. Those hacks can break updates, trip bans, or create new integrity failures.
