manual install for 1.7.2

The most important thing to understand when installing manually is that the version you create must have a consistent id. You must use the same id for every part of the installation process. In the example below we will use the id 1.7.2-LiteLoader1.7.2, if you choose a different id then you must alter this everywhere that the ID appears in order for the version to work.

installation steps

  • First navigate to the versions folder inside your .minecraft folder
  • Create a folder in versions with the id of your new version, eg. 1.7.2-LiteLoader1.7.2
  • Inside the new folder create an empty text file with the id of your new version and the extension .json, eg 1.7.2-LiteLoader1.7.2.json
  • Open the new file with a text editor and paste in the following JSON code:
    "id": "1.7.10-LiteLoader1.7.2",
    "time": "2013-10-25T14:00:00+01:00",
    "releaseTime": "2013-10-25T14:00:00+01:00",
    "type": "release",
    "minecraftArguments": "--username ${auth_player_name} --version ${version_name} --gameDir ${game_directory} --assetsDir ${game_assets} --uuid ${auth_uuid} --accessToken ${auth_access_token} --tweakClass com.mumfrey.liteloader.launch.LiteLoaderTweaker",
    "libraries": [
            "name": "com.mumfrey:liteloader:1.7.2",
            "url": ""
            "name": "net.minecraft:launchwrapper:1.9"
            "name": "org.ow2.asm:asm-all:4.1"
    "mainClass": "net.minecraft.launchwrapper.Launch",
    "minimumLauncherVersion": 16,
    "inheritsFrom": "1.7.2",
    "jar": "1.7.2"
  • If you are using a different id, then you must change the value of id at the top of the file to match
  • If you wish to inherit from a different version, for example a version of Minecraft Forge, then change the inheritsFrom value to indicate the version to inherit from
    • If you inherit from a different version, you must copy the minecraftArguments value from the other version and append: –tweakClass com.mumfrey.liteloader.launch.LiteLoaderTweaker
  • Save the file and run the launcher
  • Create a new Profile and select the version you just created.
  • Launch the game and liteloader will be downloaded and installed automatically.
