D3D12.dll

D3D12.dll is missing

What it means

The program needs Direct3D 12, which only exists on Windows 10 and 11 with a current graphics driver.

Common causes

How to fix it

  1. Check dxdiag: the feature levels must include 12_0 or higher.
  2. Remove the old graphics driver with DDU in Safe Mode, then install the current driver from NVIDIA, AMD or Intel directly.
  3. Install pending Windows updates; DirectX 12 ships with Windows.
  4. If the GPU does not support DirectX 12, the game cannot run on it; there is no DLL that fixes that.
