Manually Install Mods from a Converted .mrpack ZIP
If you do not use any third-party launcher, you can still play the modpack by manually copying mod JAR files into the standard .minecraft/mods folder.
Steps
Install the mod loader
Run the Fabric / Forge / NeoForge installer for the target Minecraft version.
Locate .minecraft
- Windows:
%APPDATA%/.minecraft - macOS:
~/Library/Application Support/minecraft - Linux:
~/.minecraft
- Windows:
Extract the ZIP
Open the converted ZIP and drag the
mods/folder into.minecraft. Merge with any existingmodsfolder.Copy configs and resource packs
Also drop
config/,resourcepacks/, andshaderpacks/(if present) into.minecraft.Launch the modded profile
From the vanilla launcher, choose the Fabric/Forge profile and play.
Why this works
This is the original, pre-launcher way to play modded Minecraft. The converter produces a ZIP whose internal layout matches .minecraft exactly, so the copy is one-to-one.
