The usual cause of ChimeraX not starting on Windows is that your graphics driver has some problem. ChimeraX uses the Qt window toolkit and that needs working OpenGL to render user interfaces, so the program just quits on startup if that is not working. The solution is to update your graphics driver. Tom
