What to Do When a Mod Says It Needs Puzzles Lib but You Cannot Find It

You installed a mod, launched the game, and got told Puzzles Lib is missing. This is the single most common reason players encounter this library at all. Here is how to resolve it without guesswork.

Confirm the Mod Really Needs It

Open the page or documentation for the mod that failed. Its requirements section will list Puzzles Lib if it depends on it. Some mods list it as required, others as optional for certain features. If it is required, you must have it. If it is optional, the mod may still run without it, just with fewer features.

Get the Right Build

Download Puzzles Lib for the same mod loader and the same game version as the mod that needs it. A mismatch here is the usual reason a freshly downloaded library still does not satisfy the dependency. Double-check the loader name and the game version before assuming the download is wrong.

Verify It Loaded

After adding it, start the game and open your mod list. Puzzles Lib should appear there. If it does not, the file is in the wrong folder, the wrong loader build, or the wrong game version. Once it shows up and the dependent mod also shows up without errors, you are done. There is nothing to configure afterward; the library simply enables the other mod to run.
