Your game won't start because of Easy Anti-Cheat (EAC) And you're frustrated when you see the launcher crashing or an error like 30005? Don't worry: these issues are common and, in the vast majority of cases, can be resolved with a few basic adjustments. Here, you'll find a clear and complete guide to getting EAC working properly.
This content brings together everything we've seen in reliable answers and forums (including Microsoft support and user input) and rewrites it directly in Spanish, so you don't have to jump from tab to tab. We've also added nuances and safety warnings where appropriate so you can follow each step wisely.
What is Easy Anti-Cheat and why it can fail
Easy Anti-Cheat is an anti-cheat service Many PC games incorporate this feature to detect unauthorized software and maintain clean games. It works in the background, and if something blocks it or breaks, the game may refuse to start.
Among the most typical triggers are damaged files from the EAC itself, insufficient permissions when running the game or service, a EAC service stopped or in manual start, conflicts with antivirus/firewall and sometimes a Windows without updating which drags incompatibilities.
It is important to understand that EAC is not a simple executable: includes a system service and a driver like the EasyAntiCheat.sys file. If any of these items become corrupted or blocked, the game will notice and crash your startup.
A practical note before we get started: If you recently tapped advanced settings or installed security softwareKeep this in mind. Many issues arise after changes like this and are resolved by reverting them or creating exclusions.
Most common errors and symptoms (including 30005)
When Easy Anti-Cheat fails, it is common to see immediate game closures without message, generic “EAC is not installed” warnings or specific codes like 30005, which frequently appears in popular titles and is linked, as Microsoft support explains, to EAC service preventing startup.
In the Microsoft Community, a specialist indicated that Error 30005 is usually resolved repairing EAC with your assistant, enabling the service in services.msc, and, if necessary, deleting the file EasyAntiCheat.sys so that it regenerates when the game is restarted. These are patterns that are repeated and work on most devices.
You will also see in some threads complementary recommendations such as temporarily disable antivirus to check if it blocks EAC, or run the game and the EAC itself with administrator permissionBelow you'll see how to do this safely and without leaving your PC exposed.

Quick checks before touching anything
Before moving on to deeper changes, it is worth doing three express checks that solve a surprising number of cases without complications.
1) Run the game as administrator: Go to the game's executable file (or its shortcut), open Properties > Compatibility tab and check “Run this program as administrator”. Apply and accept. This will prevent you from having to deal with permission lockouts on system folders or in the EAC.
2) Make sure Windows is up to date: Go to Settings > Windows Update and applies all pending updates. Many times a system patch adjusts compatibilities that EAC needs to load its driver without errors.
3) Try temporarily disabling your antivirus- Some security engines interpret EAC as suspicious and slow it down. Disable it for a moment, try starting the game, and if it now works, create a exclusion for Easy Anti-Cheat (EAC) and for the game folder, and then reactivate the antivirus.
Important Safety Notice: Disabling protection leaves you more exposed. Use it only as a test and re-enable it as soon as possible. If you find that this was the problem, The correct solution is to add exclusions, do not leave the antivirus turned off.
Repair Easy Anti-Cheat with its wizard
Easy Anti-Cheat includes its own tool that detects and repairs inconsistencies upon installation. Using it is quick and is often a godsend when there is minor corruption.
Recommended steps with the EAC wizard: Locate the Easy Anti-Cheat folder within the game installation (or whatever path your platform uses), open EasyAntiCheat.exe, select the game you are having the problem with and click on "Fix". Wait for it to finish without interruptions.
When you're done, close everything, and launch the game againIf the problem was in the module's internal files or configurations, the repair usually leaves it clean and ready.
If the wizard doesn't detect anything but you're still the same, don't worry: There are still effective actions to be taken related to the EAC service and the regeneration of its controller, which you will see below.
Activate and configure the Easy Anti-Cheat service
One of the critical points cited in Microsoft support for the error 30005 is the EAC service stopped or misconfigured. Make sure it boots and stays in Automatic to avoid crashes on startup.
Do the following: press Windows + R, writes services.msc and press Enter. In the list, locate the service Easy Anti-Cheat, double-click and press "Start" if you are detained.
In that same window, change the Startup type to “Automatic”, then “Apply” and “OK.” This setting ensures that the service is available when the game wants to load EAC.
Now close and reopen the gameIf the problem was simply that the service wasn't active, you should be able to enter without any problems. If not, skip to the next section.
Remove EasyAntiCheat.sys to regenerate it
When the EAC driver gets corrupted, delete EasyAntiCheat.sys force its clean recreation upon relaunching the game. This step has been recommended by Microsoft technicians in cases where the problem persisted after repairing the EAC.
To apply it, go to the Easy Anti-Cheat folder within the corresponding installation, look for the file EasyAntiCheat.sys and delete it. Don't delete anything else. Then try starting the game so that EAC reinstall your driver automatically.
If Windows won't let you delete because the file is in use, restart the pc and repeat the attempt before opening the game or launcher. Another option is to perform the deletion from Safe Mode, but a normal restart is usually enough.
After this step, and combining it with the EAC Wizard Repair and the service is automatic, most problematic installations are fixed and there is no trace of 30005 or similar blockages.
Antivirus and exceptions: how to make it work
Security engines can be especially zealous with anti-cheat modules. If you checked that When temporarily disabling the antivirus the game starts, it is time to create exclusions so as not to sacrifice protection.
In your security suite, add as except the game folder and the Easy Anti-Cheat folder. Look for options like “Exclusions” or “Allow,” and include EAC routes and processes. Then, reactivates protection and try the game again.
Remember: keeping your antivirus disabled isn't a solution, it's a dangerous fix. The correct thing to do is to identify and exclude EAC, as suggested by users and technicians, so that both coexist without friction.
If you also use a strict firewall or additional anti-malware software, check that is not blocking communications that EAC needs to validate. If in doubt, create permissive rules for the EAC executable.
