Knowing this will allow me to provide more precise extraction instructions or verify the content's safety.

If the extraction fails, it means one of the parts (not necessarily part 13) is corrupted. Re-download the affected part.

Right-click the first part and select "Extract Here" (or "Extract to..."). The software will automatically combine all 13+ parts into the final file(s). Troubleshooting
