Issue:
During installation, an error dialog appears stating "Required installation: Extract core package," preventing the software from being installed .
Causes:
The core package files—ZWCAD.7z in the msi\ZWCAD folder and ZWCADLP.7z in the ZWCADLP folder—have not been extracted from the installation package.
Solution:
- Open the unzipped installation folder. Extract ZWCAD.7z (in msi\ZWCAD) and ZWCADLP.7z (in msi\ZWCADLP) to their respective current folders.
- Run the software installation again. The installation will proceed normally.
