Issue:

When the OpenGL version is too low, ZW3D may experience crashes on opening. In such cases, it's not possible to check the OpenGL version within the software. So, how can I check the OpenGL version from outside the software?

Solution:

  1. Open the Run dialog using Win+R keyboard shortcut, then type cmd to open the Command Prompt.
  2. Drag the DetectSupport.exe utility from the installation directory of ZW3D into the Command Prompt.
  3. After the path, type  -t opengl -i and press Enter. This will allow you to view the OpenGL version.
  4. After performing the above steps, you can determine whether the software not opening is because of the issues with the graphics card or not.
