Installing UEFN on Windows

Let's get the editor onto your PC. This is the one part that's pure setup — once it's done, you won't repeat it.

Step 0 — Check your PC can run it

UEFN is a real game-development tool, so it asks for a reasonably capable machine. Epic's published minimums look roughly like this (always check the live page linked at the bottom, since they update it):

OS: Windows 10 64-bit (or newer)
RAM: 16 GB or more recommended (8 GB is painful)
GPU: A dedicated graphics card with up-to-date drivers
Disk: Plenty of free space — UEFN plus Fortnite is tens of GB, and projects grow
Account: A free Epic Games account

Not sure if your PC qualifies? Note your RAM and graphics card, and we can sanity-check them together before you spend time downloading.

Step 1 — Install the Epic Games Launcher

Everything Epic installs through one app, the Epic Games Launcher.

Go to https://www.epicgames.com/store/download and download the launcher.
Install and open it.
Sign in (or create a free Epic account).

Step 2 — Install UEFN

In the launcher, find the Unreal Editor for Fortnite section.
- It's usually reachable from the Fortnite tab — look for "Create" or "Unreal Editor for Fortnite," then an Install button.
Click Install and let it download. This is the big one; grab a coffee.
You may also be prompted to install/update Fortnite itself — UEFN needs it, since your islands run in Fortnite.

The launcher's layout shifts between updates. If the exact wording differs from above, look for anything labeled UEFN or Unreal Editor for Fortnite — that's the install you want.

Step 3 — Launch UEFN for the first time

Click Launch on Unreal Editor for Fortnite.
First launch is slow — it compiles shaders and sets things up. This is normal; let it finish.
You'll land on the Project Browser — a window offering templates and recent projects.

If you see the Project Browser, you're done — UEFN is installed and working. We'll create an actual project in the "Publish your first island" lesson.

If something goes wrong

Install stuck or failing? Restart the launcher; check you have enough free disk space.
UEFN won't launch / crashes on startup? Update your graphics drivers (NVIDIA/AMD/Intel) — this fixes a large share of first-launch crashes.
Can't find UEFN in the launcher? Make sure the launcher itself is fully updated, then re-check the Fortnite/Create area.

Once UEFN opens to the Project Browser, mark this complete — next we'll tour the editor so the panels stop looking intimidating.
