Answer 1

Follow this recipe:

1. Check that the file exists
2. Try to open the file in ZIP tool (7z, WinZip, ...)
3. Check that the file has the correct size; compare it to a "known good" copy
4. Copy the known good copy into the place of the file. If the error goes away, your hard disk may be dying.
5. Download the "known good" copy again to make sure it's still good.
