D3DCOMPILER_47.dll

D3DCOMPILER_47.dll is missing

What it means

The program needs the Direct3D shader compiler from the DirectX runtime, which old installs and some clean systems lack.

Common causes

• The DirectX End-User Runtime is not installed
• A game skipped its redistributable step
• Windows is missing an update that ships the DLL

How to fix it

1. Install the DirectX End-User Runtime from Microsoft; it also fills in d3dx9, d3dx11 and XInput.
2. Run the game's own redistributable from its _CommonRedist or redist folder.
3. Install pending Windows updates, then restart.
4. Only as a last resort, copy the DLL from the game's redist folder, never from a download site.
