Issue:

When starting ZWCAD, only the loading screen is displayed, but the software itself won't start. How to fix this?

Causes:

Incompatibility with the hardware acceleration feature in newer ZWCAD versions may prevent the software from launching.

Solution:

  1. Navigate to the ZWCAD installation folder (example: C:\Program Files\ZWSOFT\ZWCAD ****). Locate the file openglmesa.dll and make a copy.
  2. Rename the copied file to opengl32.dll. Restart ZWCAD.
