Fortnite won't launch on PC? 8 fixes that actually work

✓ Reviewed & updated June 2026

By the ErrorAway Team · Hands-on tested on Windows 10 & 11

You hit Launch in the Epic Games Launcher and Fortnite just… doesn't show up. Maybe the button greys out for a second, maybe the anti-cheat splash appears and vanishes, or maybe you're stuck on a black loading screen forever. It's a common problem on Windows and almost always fixable in a few minutes — usually it's corrupted game files, the anti-cheat, or a driver issue, not your account.

Work through these in order. The first three solve the majority of launch failures.

Quick checklist

  1. Restart your PC and close all Epic processes
  2. Verify Fortnite's files in the Epic Games Launcher
  3. Run the Epic Games Launcher as administrator
  4. Update Windows and your graphics driver
  5. Repair Easy Anti-Cheat
  6. Allow Fortnite through firewall and antivirus
  7. Disable conflicting overlays
  8. Reinstall Fortnite as a last resort

Why Fortnite won't launch

The usual causes are corrupted game files, a problem with Easy Anti-Cheat (which Fortnite must run to start), an outdated graphics driver, or antivirus blocking the launch. Each fix below targets one of these.

The 8 fixes

1

Restart and close all Epic processes

A stuck launcher or game process in the background can block Fortnite from starting.

  • Press Ctrl + Shift + Esc and end every Epic Games Launcher, Fortnite and EpicGames task.
  • Or simply restart your PC, then open the launcher.
2

Verify Fortnite's files

Corrupted or missing files are the number-one cause. Verifying replaces only the broken files and keeps your progress.

  • Open the Epic Games Launcher → Library.
  • Click the three dots under Fortnite → Manage.
  • Click Verify and wait for it to finish, then launch.
3

Run the Epic Games Launcher as administrator

Permission issues can stop Fortnite and its anti-cheat from launching.

  • Right-click the Epic Games Launcher icon → Run as administrator → Yes.
  • Make it permanent via Properties → Compatibility → Run this program as an administrator.
4

Update Windows and your graphics driver

Fortnite is sensitive to outdated drivers, a frequent cause of crashes on launch.

  • Go to Settings → Windows Update → Check for updates and install everything.
  • Update your graphics driver from NVIDIA, AMD or Intel, then restart.

Repair Easy Anti-Cheat

Fortnite won't start if Easy Anti-Cheat is broken. Repairing it fixes a huge share of launch failures.

  • Open the Fortnite install folder. The default is C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\EasyAntiCheat.
  • Run EasyAntiCheat_Setup.exe.
  • Select Fortnite and click Repair Service.
  • Restart your PC and launch Fortnite.
6

Allow Fortnite through firewall and antivirus

Security software sometimes blocks Fortnite or its anti-cheat from connecting.

  • Search Allow an app through Windows Firewall and make sure Fortnite, the Epic Games Launcher and EasyAntiCheat are ticked for Private and Public.
  • Add the Epic Games and Fortnite folders to your antivirus exclusions.
7

Disable conflicting overlays

Game overlays and capture tools can clash with Fortnite's anti-cheat and stop it launching.

  • Turn off in-game overlays (Discord, GeForce Experience/NVIDIA App, Xbox Game Bar).
  • Close other capture or recording software, then launch Fortnite.
8

Reinstall Fortnite as a last resort

If nothing works, a clean reinstall replaces any corrupted files. Your account, skins and progress are stored online, so nothing is lost.

  • In the Epic Games Launcher → Library → three dots under Fortnite → Uninstall.
  • Restart your PC, then reinstall Fortnite from the Library.
  • Launch and log in.

Frequently asked questions

Will I lose my skins or progress if I reinstall Fortnite?

No. Your account, skins, V-Bucks and progress are all tied to your Epic account online. Reinstalling only replaces the game files on your PC.

Fortnite shows the anti-cheat screen then closes. Which fix?

That points straight to Easy Anti-Cheat. Repair it (fix 5) and make sure it's allowed through your firewall and antivirus (fix 6) — that combination resolves most anti-cheat launch failures.

Do I need to reinstall the whole launcher too?

Usually not. If only Fortnite fails to launch, verifying its files (fix 2) and repairing Easy Anti-Cheat (fix 5) are enough. Reinstall the launcher only if it's broken for every game.

Is it safe to allow Easy Anti-Cheat through the firewall?

Yes. Easy Anti-Cheat is the official anti-cheat Fortnite requires, and it needs network access to verify your game. Allowing the official files is expected and safe.
