Why Is xinput1_3.dll Missing? This error usually pops up for a few specific reasons:
Modern Windows versions (10 and 11) come with newer DirectX files, but many older or mid-generation games require "legacy" files from the DirectX End-User Runtimes (June 2010) package.
Go to the official DirectX End-User Runtime Web Installer page. Download and run the installer.
A game installation might have failed to include the necessary dependencies.
Sometimes, the error is triggered by outdated video card drivers that can't properly communicate with the DirectX libraries. Check the NVIDIA, AMD, or Intel websites for the latest updates. 4. Run a System File Checker (SFC) Scan
During installation, you might be asked to install the Bing Bar; you can uncheck this to keep your browser clean. 2. Check the Game’s Own Folder

This is the "gold standard" fix. It scans your computer for any missing DirectX files and downloads exactly what you need.
