DirectX error

The game asks for d3dcompiler or XInput how to fix

Download DirectX Legacy Runtime.
Run the installer as administrator.
Do not manually copy DLL files to System32/SysWOW64.
Restart the game after installation.

Why this error appears

D3DCompiler_43.dll error.
XInput1_3.dll error.

FAQ

Quick answers on the error

Can I download just one DLL file?

Better to install the runtime package first: it adds related components and reduces version error risk.

Why is DirectX installed but the error persists?

System DirectX and legacy components are different things. A game may require an old library not present in new Windows.

When won't the runtime help?

If the graphics card does not support the required Feature Level or the driver is damaged, the GPU and driver issue must be fixed.
