If you're on a laptop or a desktop with dual GPUs (both an integrated chip and a dedicated card), you need to force Windows to use the high-performance GPU for Lumion.
Third-party software that overlays data onto your screen can interfere with DirectX initialization. Try closing programs like:

Many laptops and workstation desktops utilize hybrid graphics to save power. If Lumion initializes using integrated graphics, it will trigger the D3D9 crash.
If you're using a laptop or a desktop with both integrated graphics (e.g., Intel HD Graphics) and a dedicated GPU (NVIDIA or AMD), Lumion might default to the slower integrated chip. The error occurs because integrated graphics often lack the performance and feature set required by Lumion. According to Lumion support documentation, if your PC is using the slow Intel HD graphics chip, you are highly likely to encounter this error.
