Prism Launcher keeps every setup in its own instance, so your LeiCraftClient setup doesn't touch your other modpacks. Its built-in mod browser can download LeiCraftClient from Modrinth and pick up its dependencies.
What you need
- Prism Launcher from https://prismlauncher.org, with your Microsoft account added.
- Nothing else to download if you install from Modrinth. If you prefer the jar from our website, get it from the download page.
Install
Create the instance
- Click Add Instance.
- On the left, choose Custom.
- Pick Minecraft 26.3 from the version list.
- Under Mod Loader, choose Fabric. The newest loader version is fine (0.19.5 or newer).
- Give the instance a name and click OK.
Open the mod list
Select the new instance and click Edit. In the window that opens, choose Mods on the left.
Add LeiCraftClient
- Click Download Mods.
- Choose the Modrinth tab and search for
LeiCraftClient. - Click LeiCraftClient, then Select mod for download.
- Click OK. Prism also finds the mods that LeiCraftClient needs and adds them to the list.
- Check that Fabric API and Fabric Language Kotlin are in the list, then confirm the download.
- Download the LeiCraftClient jar from the download page.
- Click Add File and choose the jar. You can also click View Folder and copy the jar into the folder that opens.
- Click Download Mods, search on the Modrinth tab and add Fabric API and Fabric Language Kotlin the same way.
Check the mod list
The Mods list should now show three mods: LeiCraftClient, Fabric API and Fabric Language Kotlin. Make sure all three are enabled (checked).
Start the game
Close the edit window and launch the instance (double-click it). Look for the LeiCraftClient button on the title screen, below the Realms button. If you see it, LeiCraftClient is installed.
Next: link your account
You can already see other players' capes and cosmetics. To wear your own, link your Minecraft account: Link your account.
Troubleshooting
- The game stops with an error about missing or incompatible mods. The error names the missing mod. Most often it is Fabric Language Kotlin or Fabric API. Add it with Download Mods.
- LeiCraftClient isn't in the search. Check that the instance is on 26.3 with Fabric (or Quilt) as the mod loader.
- You already have a 26.3 instance with other mods. You can add LeiCraftClient there too, as long as it runs Fabric.
