Xinput1_3.dll is a library of functions used by various games and programs. The absence of this file makes it impossible to run the application dependent on it. The problem can be solved in two ways: by installing DirectX or manually copying the file. Let's consider both ways.
Xinput1_3.dll is part of the DirectX runtime. Therefore, the first thing to do is to update this DLL package, and our file will appear in the system accordingly. I have to say that DirectX is often installed along with the games that need it. However, if this package was not installed during the installation of the game, you can install it separately.
Manually copying a file
The first method is preferable, but if it is not suitable for you, you can install the file manually. To do this, you need to download it from our website and put it in the right folder. Detailed instructions on manual installation of the file is located in the archive with the file itself. Pay attention that there are files from the 32-bit and 64-bit DirectX sets. If you have 64-bit Windows, try a 64-bit file first, if it doesn't fit - download a 32-bit one.
For reference: The DLLL is a set of universal functions. Xinput1_3.dll, in particular, contains functions for interaction of the game with speakers and microphone, gamepads, laptop battery, various controllers, etc. If you are a programmer, you can find more information about the functions and their syntax on the MS Developer Network.
