When you run SCARM or open the 3D Viewer, you may encounter an error message, saying “External exception” along with some error code.
The message may looks like the following:
The reason of this error is outside SCARM scope and is connected with graphics card, graphics drivers, OpenGL support and/or their settings.
The explanation is that SCARM is unable to find or initialize the OpenGL rendering subsystem in your computer and thus it cannot continue. To solve the problem, please check the following:
1. Ensure that you have the latest drivers for your graphics card and chipset. Check on the manufacturer’s web sites and update the drivers if needed.
2. Check the graphics settings. Open the Control panel/Control center of the graphics driver and set all settings, concerning 3D rendering and OpenGL to their default values.
3. Turn off all advanced graphics settings. If the error remains with the default graphics settings, try to turn off all advanced capabilities of your graphics card and to ensure that no other program or process uses the card’s 3D engine.
|There is a known issue with 3D Viewer on SiS Mirage based videocards. When you try to open the 3D Viewer, the program shows empty or corrupted window, displays an error message or crashes. The author is working to solve the problem.|
If these steps does not solve the problem, post a comment below with information about your system (Windows version, CPU, RAM, video card model, video memory size) and how and when the error appears (on start-up, when opening 3D Viewer, on particular layout, etc.) and I will try to find other solution.
