Three things stand between you and the field. One small program takes care of both modules.
The itinerary
Distances are counted in downloads. The updater, or the Steam Workshop, brings the first two.
What you need
The base game, up to date. Our servers ran Bannerlord 1.4.8 in October 2026.
About 10 GB in total: 9.5 GB for LotRMPCore and about 0.4 GB for LotRMPEvent and its twelve maps.
Not needed to install, but needed to take part in a battle.
The asset module
9.5 GB
Models, textures and animations for every people of the event. LotRMPEvent will not load without it. Both ways below install it: the updater, or the Steam Workshop.
§ 2Download
Installs LotRMPCore and LotRMPEvent and keeps both up to date. Every store, Steam included.
Already subscribed to LotRMPCore on the Workshop? The updater reuses those files instead of downloading 10.3 GB again. The game then uses the copy in your Modules folder: unsubscribe from both Workshop items afterwards, so the launcher lists each mod once.
Not code-signed yet
Download the updaterNothing to install: run it and it opens.
Hashes, scans and signatureSource code (MIT)Steam only
Subscribe to both items and Steam downloads them. Workshop updates can lag a few days behind the server while Steam reviews them; the updater is always current.

One small file. Save it anywhere, for example in Downloads. Nothing to unzip, nothing to install.
It looks where Steam, the Xbox app, Epic and GOG keep Bannerlord, and sees which of the two modules you already have. Unusual setup? Point it at the game folder yourself.
It shows both modules, which one changes and how much it will download; “Show details” lists every file. Nothing changes until you click Update. It checks every file as it goes.
Next week, open it again: it checks by itself and fetches only the files that changed.
The updater finds Bannerlord in every Steam library and installs both modules. Already have LotRMPCore from the Workshop? It reuses those files instead of downloading them again; then unsubscribe from the Workshop items, so the launcher lists each mod once.
The updater finds the game in your XboxGames folder. It downloads both modules from our server; on busy nights the LotRMPCore download (10.3 GB) waits its turn in a short queue.
The updater reads the Epic launcher’s list of installed games. It downloads both modules from our server; on busy nights the LotRMPCore download (10.3 GB) waits its turn in a short queue.
The updater reads where GOG Galaxy installed the game. It downloads both modules from our server; on busy nights the LotRMPCore download (10.3 GB) waits its turn in a short queue.
Moved or copied the game? Choose the folder by hand: the one that contains bin and Modules.
No surprises. This is everything it touches, and everything it leaves alone.
Modules\LotRMPEvent · Modules\LotRMPCore%LOCALAPPDATA%\LotRMPUpdaterIn Bannerlord’s launcher, open the Multiplayer tab and tick LotRMPCore and LotRMPEvent.
Launch Multiplayer and find the event server. Its name is posted on Discord with the teams.
The gates open Tuesdays, 20:00 Paris time. Join, wait in line, and play for your clan’s side.
Every message the updater and the game can show you, with its cause and its cure.
8 perils
Windows protected your PC
Why
The updater is not code-signed yet, and Windows SmartScreen warns about unsigned programs downloaded from the internet.
The cure
Check the SHA-256 shown on this page if you like, then click More info, then Run anyway.
Bannerlord or its launcher is running
Why
The updater opened its list of changes instead of updating: Windows does not let anyone replace files the game is using.
The cure
Close the game and its launcher (check the Task Manager for Bannerlord or TaleWorlds.MountAndBlade.Launcher), then click Update again.
Windows did not let the updater replace …
Why
Another program held one of the mod’s files open (the message names it: often the game, an antivirus scan or an open Explorer preview). The updater put everything back: your previous files are still in place.
The cure
Close the program the message names, then click Try again.
Why
You have both the Workshop copy and the local copy. That is expected.
The cure
Leave LotRMPEvent ticked: the game takes the local copy first. To use the Workshop copy again, delete Modules\LotRMPEvent.
Why
The game compares module ids and versions with the server: your LotRMPEvent or LotRMPCore is not the version the server runs.
The cure
Bring both modules up to date: run the updater, or let Steam finish updating both Workshop items (their updates can lag a few days). Then restart the game and join again.
You don't have at least one map … being played on the server, or the local map is not identical
Why
The game checks that your copy of the current map has the same name and revision as the server’s. Yours is missing or older.
The cure
Install the current package: it carries the event’s twelve maps. If the game still refuses a map, ask on Discord: the team may have updated it since. Old map copies elsewhere (for example in Modules\Multiplayer\SceneObj) can get in the way: ask on Discord before deleting anything.
Why
LotRMPEvent needs the bodies and armour of LotRMPCore. Without the Core, or with an incomplete download, the game cannot build the first Orc or Elf.
The cure
Tick LotRMPCore in the launcher. Then run the updater’s “Verify files”, or, if you use the Workshop, check in Steam that the LotRMPCore download (about 9.5 GB) finished.
Why
When the updater stops on an error, it puts your previous files back: nothing else was changed.
The cure
In the updater, open HELP and press “Send the report”: you get a short code (like LOTR-7F3K). Paste it in a ticket on Discord and the team sees what happened.
No peril matches these words. Post a screenshot of the window in the support channel on Discord.
