Redownload and it should work.
This one is really strange. I got the same error when trying to unzip that file from Mac. It unzipped on Windows fine. I remade a new zip file and it did the same thing. So I then made the zip file again but from Mac OSX. Now the file opens on Windows and Mac. I checked the other product zips that were made from Windows and they all open fine on Mac. Really not sure why this one in particular was not working on Mac.
Anyway, the new download will work
