SyncCrate
Elden Ring guide · Updated
Elden Ring Seamless Co-op for the whole group.
Seamless Co-op only connects players who run the same version with the same password. SyncCrate copies the host's SeamlessCoop folder, settings included, to every friend, and after the first time only what changed.

// 01 Why
Why Seamless Co-op sessions fail to connect
Seamless Co-op is the way most groups play Elden Ring together for a whole run. It only works when everyone has the same version of the mod and the same co-op password in its settings file.
Updates come out often, and after each one somebody is still on the old version, or typed the password slightly differently. Then the summon sign never shows up and nobody knows why.
With SyncCrate one PC hosts and the others match it. The SeamlessCoop folder, including the settings file with the password, is compared by content and only the differences are copied.

// 04 Common problems
When Elden Ring mods don't match
Friends can't see each other
Players on different versions of Seamless Co-op, or with different passwords, can't join each other's sessions.
Everyone syncs the host's SeamlessCoop folder, so the version and the password match before anyone starts the game.
A new version came out
After an update the whole group has to switch at the same time, or nobody can play together.
The host updates once. Friends sync and get the new files.
ersc_launcher.exesits next to the folder and isn't synced, so copy it once after an update that changes it.Who changed the settings?
Settings like the password, enemy scaling or how many lives the group has live in one file, and a friend's copy drifts from the host's.
The settings file syncs with the folder. When it changed on both PCs, SyncCrate asks: keep mine, use theirs or keep both.

Good to know
- Saves aren't synced. Seamless Co-op saves sit in your AppData folder, tied to your Steam account, so each player keeps their own character.
- Code is flagged. The mod's
.dllruns code on your PC, so it's flagged before it syncs and nothing changes until you approve the list. Only sync with people you trust. - Steam version. SyncCrate finds the game in every Steam library. Point it at the game's
Gamefolder if it's somewhere else.
// FAQ
Elden Ring questions
Do all players need Seamless Co-op?
Yes. Everyone needs the same version of the mod and the same password, which is exactly what syncing the host's folder gives them.
Does SyncCrate install Seamless Co-op?
It copies the host's SeamlessCoop folder. The first time, each player also needs ersc_launcher.exe next to it, from the mod's download.
Does it copy my character?
No. Saves are tied to each Steam account, so everyone plays their own character.
Can I sync other mods too?
This page covers Seamless Co-op. Mods loaded by Mod Engine 2 live in its own folder, wherever you unpacked it, and aren't synced.
