The issue with 3D viewing

Hello I am Jamshesh from Bhansali Steel

Hello, I'm having trouble with the 3D view. I have an HP laptop, model 450g2, and the 3D view does not work when I am working with the contextcapture software. The 3D view windows are completely grey, and there are no images of my reconstruction model. Can someone explain why I'm having this problem and how I can solve it?
