Install Meteor Client for the Minecraft version you use
Install Lunar Client for the same Minecraft version
Launch Lunar Client first
Open the game folder and place the Meteor Client files in the correct mods location if your setup supports it
If Meteor does not load in Lunar Client, use a separate Fabric installation instead
Run Meteor through Fabric, not directly inside Lunar Client, if Lunar blocks the mod
Make sure Fabric API is installed when required
Keep all versions compatible: Minecraft, Fabric, Meteor, and Lunar
Use one client at a time if they conflict
Check Lunar Client settings for any mod or anti-cheat restrictions
Remove incompatible mods if the game crashes
Use a separate profile for testing
If you want Meteor features, use Meteor on a Fabric client rather than relying on Lunar integration
