The “Launch Error: EasyAntiCheat not installed” error is caused by Fortnite not being able to load the “Easy Anti-Cheat” engine that ships with the game.
While the error will prevent the game from loading properly, it is usually not caused by any deep aspect of your system.
To this end, the solution to the problem should be relatively simple. If not, some additional steps may be required for it to work properly.
Causes
The main cause of the error is that the Easy Anti-Cheat application is not present.
To fix this, you need to make sure your system can a) access it b) run it.
The message that appears with this error includes:
Could not start the game
Please help us by reporting this issue: Error Code 20006
The specific causes of the problem are:
-
Fortnite can’t run Easy Anti-Cheat
-
Windows has deeper problems with your files/settings
Solution
The way to solve the problem is to reinstall the Anti-Cheat service and then make sure that the game is working properly.
This is a simple process:
1. Reinstall Easy Anti-Cheat
The first step is to make sure that the EAC is working correctly.
To do this, you must follow these steps:
-
Navigate to “C:Program FilesEpic GamesFortniteFortniteGameBinariesWin64EasyAntiCheat” on your hard drive (wherever it is installed)
-
Click on “EasyAntiCheat_Setup”
-
Click on “Repair Service”
-
try loading it again
If it works after this, it means that the problem can be considered solved.
If it doesn’t work, you may need to do a “verify” repair on the system.
2. Check the game files
The next step is to verify the installation of Fortnite.
This is relatively simple –
-
Load up the epic games launcher
-
Click on “Fortnite”
-
Select the “cogwheel” next to the green “Start” button
-
In the drop down menu, select “verify”
-
Let the process run
-
Reboot your system
-
try to play it again
After doing this, if the game works, the problem should be fixed.
3. Reinstall VC++
If the above two steps don’t work (they should), Visual C++ could be the culprit.
Visual C++ is a library that Microsoft created and distributes for use by software developers.
It basically provides additional functionality to applications.
While the system is effective, it does have a propensity to become problematic, often displaying bugs and issues, etc.
To make sure this is not a problem for your system, you should remove any instances of the VC++ redistributable package on your system, and then replace it with a fresh version:
-
In Windows 7, click “Start”, then “Control Panel” and finally “Programs and Features”
-
In Windows 10, right-click the “Start” button, select “Apps and Features”
-
In the list that appears, scroll down to the “Microsoft Visual C++ Redistributable” lists.
-
Write down which ones you have installed (pay special attention to the year and architecture)
-
After doing this, browse the internet and search for “Visual C++ Downloads”.
-
Click on the link from Microsoft titled “Latest Supported Visual C++ Downloads”
-
Download fresh copies of each of the packages you listed
-
Once this is complete, uninstall each package from your system
-
Restart your PC
-
Install each new VC++ package (the order doesn’t matter)
-
Reboot your PC again
-
try to play the game again
If more problems are found, it means that you have deeper problems with Windows.
To figure this out, it’s best to talk to someone who has more specific experience with your system. This can come in many different forms, from online communities to paying for professional help.
