Add mods to a Prism Launcher instance: match the loader and game version, add one mod at a time and test.

Adding a mod

Confirm the instance uses the mod loader the mod needs, match the Minecraft version exactly, then add one mod and launch before adding more.

Why does an instance crash after adding a mod?

Usually a version or loader mismatch, or a missing dependency. Remove the last mod added and re-check its requirements.

Overview

Create, clone, group, export, and back up isolated Minecraft instances on Windows with independent mods, resource packs, and Java versions.

How-to

Install a modpack in Prism Launcher by importing it as a new instance, then launching it unchanged first.

Overview

Install Prism Launcher on Windows 10 and 11, choose between the MSVC installer and Portable ZIP, and add Microsoft or offline profiles.

Free and open source. Sign in with the Microsoft account that owns Minecraft, then create your first instance.
