How do I install a modpack? — Minecraft

Q: Why can't I join after it installed?

You need the same modpack version in your launcher as the one on the server. A mismatch causes a "mod mismatch" kick.

Installing a modpack on your server is refreshingly simple thanks to the Modpacks tab — for most popular packs it's a single click. The panel grabs the right loader and every mod for you, so you're only a few steps from playing.

How the Modpacks tab works

The Modpacks tab is a built-in installer. When you pick a pack, it automatically fetches the matching Forge or Fabric loader and all of the pack's mods, then sets everything up for you — no manual file juggling.

Step-by-step

Open the Modpacks tab and search for the pack you want.
Click install — the panel fetches the correct loader and all the mods automatically.
When it finishes, start the server from the Console.
In your Minecraft launcher, load the same modpack version, then connect to your server.

Tip: Heavier packs need more RAM. For large modpacks, a Supreme or Ultimate plan is recommended — see our modded sizing article to match resources to your pack.
