Install UE4SS v3.0.1

• Windows 10 or 11, 64-bit.
• EARTH DEFENSE FORCE: WORLD BROTHERS installed through Steam and up to date.
• The game closed.
• Already have a UE4SS in this game? Read Already have UE4SS? first.

UE4SS and the mods are built with Microsoft's C++ compiler and need its runtime files. UE4SS.dll needs two of them, MSVCP140_ATOMIC_WAIT.dll and VCRUNTIME140_1.dll, that only recent versions of the redistributable install, so update it even if you already have one.

1. Download the installer from Microsoft: vc_redist.x64.exe. Microsoft calls it the Visual C++ v14 Redistributable.
2. Run it and click Install.
3. If it offers Repair, or says a newer version is already installed, you already have it. Close the window.
4. If it asks you to restart Windows, restart.

Get the x64 version: the game, UE4SS and all seven mods are 64-bit. Checked in the files themselves: UE4SS.dll imports MSVCP140.dll, MSVCP140_ATOMIC_WAIT.dll, VCRUNTIME140.dll and VCRUNTIME140_1.dll; every Ungodly main.dll imports MSVCP140.dll and VCRUNTIME140.dll.

1. Open the UE4SS v3.0.1 release on GitHub. On 11 Oct 2026 it was marked Latest, the newest stable UE4SS. If GitHub ever shows a newer stable release, still use v3.0.1: the mods are built for it.
2. Scroll down to Assets and click UE4SS_v3.0.1.zip (5.3 MB).
3. Save it, for example in your Downloads folder.

The same release page lists more files. You don't need any of them:

A SHA-256 checksum proves your file is byte-for-byte the official one. It takes a minute.

1. Right-click the Start button and open Terminal (Windows 11) or Windows PowerShell (Windows 10).
2. Paste this and press Enter (change the path if you saved the zip somewhere else):
   PowerShellGet-FileHash "$env:USERPROFILE\Downloads\UE4SS_v3.0.1.zip" -Algorithm SHA256Copy
3. Compare the Hash it prints with this one. PowerShell prints capital letters; that makes no difference.
   SHA-2564B47D4BCEDDD2F561A4E395BFA00924CCFC945AF576A2D0C613E6537846C57ECCopy

Using the old Command Prompt instead? certutil -hashfile "%USERPROFILE%\Downloads\UE4SS_v3.0.1.zip" SHA256 prints the same hash in small letters.

1. In Steam, open your Library.
2. Right-click EARTH DEFENSE FORCE: WORLD BROTHERS, then choose Manage and Browse local files. File Explorer opens the game's install folder. Steam names it mikan.
3. Open EDFWB, then Binaries, then Win64.

You're in the right folder when you can see EDFWB-Win64-Shipping.exe, the game itself. On most PCs the full path is one of these; you can paste it into File Explorer's address bar:

1. Double-click UE4SS_v3.0.1.zip to open it in File Explorer. Inside are six items: the Mods folder, Changelog.md, dwmapi.dll, README.md, UE4SS-settings.ini and UE4SS.dll.
2. Select all six with Ctrl + A and copy them with Ctrl + C.
3. Go to the Win64 folder from step 5 and paste with Ctrl + V.
4. If Windows asks for administrator permission (it does when the game is under Program Files), click Continue.

Your Win64 folder should now look like this:

Full size

The screenshot also shows ue4ss.rar. That's a backup on StixsworldHD's PC; you don't need it. The sizes in the table were measured from the official zip and match the screenshot.

This tells you UE4SS works before you add the mods.

1. Start the game from Steam as usual and wait for the title screen.
2. Quit the game.
3. Open Win64\UE4SS.log with Notepad.

No UE4SS.log at all? Then UE4SS didn't start. See No UE4SS.log after starting the game.
