D3D11 needed for Fortnite?

I installed Fortnite yesterday, but every time I start it the error message "A D3D11- compatible GPU (Feature Level 11.0, Shader Model 5.0) is required to run the engine." I already have the DirectX 12 version, but the error is displayed. I have an Intel G41 chipset graphics card and the latest drivers are installed. What's the problem? Thank you!

Too bad pc think what are your pc parts?

GPU: G41 Express Chipset

CPU: Pentium Dual Core E5700 @ 3.00GHz
