Hi Anthony, Have you tried to open the demo project? If it's the first time you open it, it will take couple minutes to open. Next times will be much faster. If the Tekla BIMsight freezes after first model is loaded (the progress bar is at the end) or if no models in the project, when the 3D is opened. In this case I would suggest you to update your graphics card drivers. I'm using Tekla BIMsight on Windows 10 and it works just fine. Best regards, Marko Myllymaa
