When a zip file becomes corrupted, it can mean one of a few things. The most common reason for zip file corruption is due to incomplete downloading or transfer of the file. When only part of the file is transferred, the zip file can become unreadable or damaged. Other causes of zip file corruption include errors during creation or extraction of the file, or damage to the storage media where the file is saved.
If the answers above didn't work then you should also try:
- Use a different zip archive
- Use a different extraction method
- Use a different zip file repair tool
- Try a different computer
- Contact the zip file creator for support
