How To Fix Integrity Error in Rust

Rust is one of the older and popular multiplayer-only open-world survival video games that has been developed by Facepunch Studios and launched way back in 2013. It was in early access mode initially and currently one of the highest-rated PC games on Steam with positive reviews due to its real-life-like gaming experience. Now, if in case, you’re experiencing the Integrity Error in Rust, you can follow this troubleshooting guide to fix it.

Rust only aims to come across various life survival struggles such as hunger, thirst, cold, shelter, protecting yourself from others, using fire to keep yourself warm, killing animals, and more. But plenty of players are getting affected by the “Disconnected: Integrity Error: Unknown file version: Bundles\shared\prefabs.bundle” error message while connecting to the game server. Meanwhile, most of them also receive the ‘Unknown EAC Error’.

How To Fix Integrity Error in Rust

Well, to be very precise, the particular error “Disconnected: EAC: EAC Disconnected” is mostly troubling the Rust players whatsoever. ‘EAC’ stands for ‘EasyAntiCheat’, a security service that protects the game and other genuine players from cheaters and hackers. This kind of error mainly occurs whenever the EAC client fails to establish a valid connection to the game servers and the error pops up every time.

How To Fix Integrity Error in Rust

Coming to the possible reasons behind such an issue, it seems that missing or corrupted game files on your computer may also trigger the EAC disconnected error. Whereas running the game executable or client executable without the admin permission can also trigger the integrity error. Additionally, issues with the internet connection or even issues with the installed EAC certificate can be another reason.

1. Verify Game Files

Rust PC gamers on Steam can follow the below steps to easily verify and repair the missing or corrupted game files because in some cases some of the internal game files may get affected due to several reasons. It’s always recommended to repair your game files from the Steam client to cross-check that nothing is creating a problem with the game files. To do so:

Open the Steam client > Make sure that you’re logged into your valid account.
Click on Library > Right-click on Rust from the list.
Click on Properties > Select the Local Files tab.

Next, click on Verify Integrity of Game Files.
Wait for the process to complete. Once done, make sure to restart the computer to apply changes.

Finally, you can run the game to check whether the Integrity Error in Rust has been fixed or not.

2. Give Admin Privilege

Well, giving the admin privilege to the game executable or even the client executable file is necessary in order to properly run the game by any means. This is one of the most common issues for PC users because they don’t run the program with admin access mostly and it ends up with multiple issues with the applications or games.

Right-click on your Steam.exe file or the desktop shortcut file.
Click on Properties > Go to the Compatibility tab.
Checkmark Run this program as an administrator.
Now, click on Apply and then OK to save changes.
Finally, you’re good to go.

Again you’ll have to give admin access to the game file. To do that:

Open the Steam client > Make sure that you’re logged into your valid account.
Click on Library > Right-click on Rust from the list.
Click on Properties > Select the Local Files tab.
Select Browse Local Files > Right-click on the Rust.exe file.
Select Properties > Go to the Compatibility tab.
Enable the ‘Run this program as an administrator’ checkbox.
Click on Apply and then OK to save changes.

3. Power Cycle Your Router

If in case, your game is still facing the error then make sure to check your internet connection. Sometimes a slower internet speed or unstable network signal can also trigger multiple server connectivity-related issues for the online multiplayer video games. Additionally, you should try using a wired (ethernet) connection if you’re using a Wi-Fi connection or vice-versa to cross-check the problem.

Meanwhile, you should also perform the power cycle to your Wi-Fi router because sometimes the router system can store several temporary cache data which troubles you a lot. To do this:

Turn Off the Wi-Fi router > Make sure that LED indicators are completely turned off.
Now, disconnect the power cable from the router > Wait for around 30 seconds.
Then plug back the power cable in and turn on the router again.
Connect to the Wi-Fi network and check if the Integrity Error in Rust or EAC Disconnected error has been resolved or not.

4. Set DNS Settings to Default

if you’re still facing the problem, make sure to turn on the UPnP settings on your router’s admin panel. Just log into your router’s admin panel via a web browser and go to the Advanced / Port Forwarding option. Next, make sure to enable the UPnP option.

Additionally, you should check whether you’ve selected the DNS address settings to its default mode or not. To do so:

Click on the Wi-Fi or network icon from the Taskbar.
Click on Network & Internet Settings > Click on Change adapter options.
Right-click on the active internet adapter that you’re using.
Select Properties > Double-click on Internet Protocol Version 4 (TCP/IPv4).
Make sure to select Obtain an IP address automatically and Obtain DNS server address automatically.
Now, click on OK to save it and restart your computer to apply changes.
Finally, you should be able to resolve the Integrity Error in Rust.

5. Install EasyAntiCheat Certificate

However, if the above method doesn’t fix the problem, try installing the EasyAntiCheat Certificate on your computer properly. The chances are high that you’re getting the EAC disconnected error while trying to launch Rust because the EAC certification isn’t properly installed and denied to run.

We assume that you’ve already enabled the administrator permission for the Steam client. If not, do that first.
Now, open the Steam client > Make sure that you’re logged into your valid account.
Click on Library > Right-click on Rust from the list.
Click on Properties > Select the Local Files tab.
Select Browse Local Files > Next, right-click on the Rust.exe file.
Choose the Open file location option from the menu.
Locate the EasyAntiCheat folder and open it.
Search for the .cer extension-based certificate files from the folder.
From those files, there is a Certificate Import Installer (looks like paper with an orange ribbon).
Now, double-click on that file to open the Certificate Import Wizard.
Select Local Machine from the Store Location option > Click on Next to continue.
Select Automatically select the certificate store based on the type of the certificate and click on Next.
Follow the on-screen prompts step-by-step until you see the Completing the Certificate Import Wizard message.
Finally, click on Finish to complete the process > Restart your computer.

This may gonna help you to resolve the Integrity Error in Rust or EAC Disconnected error completely.

6. Reinstall the Game

However, if none of the methods worked for you, just uninstall and reinstall the Rust game on your computer to terminate any kind of possible issues (if any). Don’t worry about the saved game data because it’ll be kept safe to the Steam server. So, just log into your existing Steam account and then reinstall the game to get back your game progress.

Keep in mind that both the Steam client and Rust are closed completely. You can also go to Task Manager (Ctrl+Shift+Esc) to close Steam & Rust from the Processes tab (if any).
Now, press Windows + I keys to open Windows Settings.
Click on Apps > Scroll down to the list of installed programs and locate Rust.
Single-click on Rust and select Uninstall.
Follow the on-screen instructions to complete the uninstallation process. If prompted by UAC, click on Yes to allow the process.
Once the game deleted, make sure to close all tasks, and restart your PC/Laptop.
Next, launch the Steam client > Search for the Rust game.
Click on Install to reinstall the Rust game on your computer again.
Enjoy!
