Issue:

ZW3D has been in use for a while, but one day when opened the software, it displayed the following screen and then crashed and cannot access the software.

Solution:

In this case, you can try cleaning the user folder.

  1. Press Win+R on the keyboard to open the Run dialog, then type %appdata% and press Enter.
  2. Locate the folder name with your ZW3D version under the folder ZWSOFT(for example ZW3D 2024), right-click on it, select Rename (recommended, which you can report to ZWSOFT for locating the specific reason) or Delete, and then restart the software.
