Drop In the Loader
UE4SS is the scripting system that runs Lua mods inside Unreal Engine games. Install it once into Win64 and the game injects it automatically every launch — this is links 01 → 02 of the chain.
When the game starts it tries to load Windows’ own dwmapi.dll. UE4SS ships a stand-in dwmapi.dll that the game loads instead, which quietly boots UE4SS.dll, which then reads your Mods folder. That hand-off is the “injection chain” — no game files are modified, and removing the loader is as simple as deleting the files.

Stage 01 · AcquireDownload UE4SS from the official repo
Grab the latest release straight from the source — the RE-UE4SS GitHub Releases page. Avoid random re-uploads.
Open RE-UE4SS Releases ↗
On the latest release you'll see two flavours. Pick based on what you want:
UE4SS_v{version}.zip— the basic / end-user build. Silent, no console window. This is the one most players want.zDEV-UE4SS_v{version}.zip— the developer build. Same loader, but the UE4SS console window is visible by default, which is genuinely useful the first time so you can watch the overhaul load and confirm it worked.
PRO MOVEFirst-timer? Grab the zDEV buildThe visible console makes verification trivial — you'll see the overhaul's startup banner print in real time. Once you're confident everything works, you can swap to the basic build, or just leave it; the console does no harm.

Stage 02 · ExtractUnzip everything into
Win64Open the
.zipand extract its contents directly into the game's executable folder — the sameWin64you bookmarked in Chapter 01:...\HYPERCHARGE Unboxed\Unboxed\Binaries\Win64\You're placing the files beside
Unboxed-Win64-Shipping.exe, not into a new subfolder of their own. HYPERCHARGE is a standard UE4 title and needs no special game-config patch, so the plain extract is all it takes.CAUTIONExtract contents, not the folderIf your unzip tool drops a single
UE4SS_v...folder intoWin64, go one level in and move the files out sodwmapi.dllsits directly next to the.exe. The proxy only works from the executable's own folder. -
Stage 03 · Verify the layoutConfirm the files landed correctly
After extracting,
Win64should now contain the loader files alongside the game. The reference install uses the classic flat layout — everything sitting right inWin64:Win64/ ├─ Mods/ UE4SS mods live here (Chapter 03) │ ├─ BPModLoaderMod/ built-in UE4SS mods │ ├─ ConsoleEnablerMod/ unlocks the in-game console │ ├─ ... (other built-in mods) │ └─ mods.txt the enable list ├─ dwmapi.dll the proxy — loaded first ├─ UE4SS.dll the scripting system ├─ UE4SS-settings.ini UE4SS configuration ├─ UE4SS.log created on first launch └─ Unboxed-Win64-Shipping.exe the game
NOTETwo valid layouts — both workNewer UE4SS builds default to tucking
UE4SS.dll, the settings and theModsfolder into aue4sssubfolder, leaving onlydwmapi.dllinWin64. The older flat layout shown here (and in the screenshots below) is fully supported for backwards compatibility. Whichever your download produces, the rule is the same: put the mod in whateverModsfolder UE4SS is already using.Here's exactly what a correct flat install looks like on the reference machine — click either shot to view it full size:

Stage 04 · BootLaunch once and let UE4SS inject
Start the game normally through Steam. The first launch is doing real work behind the scenes — the proxy fires, UE4SS initialises, and it writes its
UE4SS.loginto the same folder. Let it reach the main menu, then quit.Two signs it worked:
- A fresh
UE4SS.logappears (or updates) inWin64with a current timestamp and no error lines near the bottom. - If you used the zDEV build, a separate console window appears alongside the game showing UE4SS booting.
- A fresh

Stage 05 · Prove itOpen the in-game console
UE4SS ships with a console-unlocker mod. In-game, press the console key — by default that's
~/@orF10. If a console drops down, UE4SS is live and reading mods. That's your green light to install the overhaul.PRO MOVEHot-reload is your friendOnce mods are loaded you can press
Ctrl + Rto reload all Lua mods without restarting the game. You'll lean on this in Chapter 04 when tuning the overhaul's config.
Loader confirmed?
If the console opens and the log is clean, links 01 and 02 of the chain are done — the game now loads UE4SS on every launch. Time to give it something to run.
