I see that ockham seemed to have a success,

WinRAR was able to repair the ZIP, and the repaired version extracted properly.

That may be ... or may not be. 

I wouldn't trust those extracted files at all. 

If the ZIP was corrupted during the download and the winZIPintegrity checks determined that the ZIP file was corrupted, how could any other software possibly correct the extraction by 'guessing' the correct values?  HINT: corrupt ZIP file means the downloaded data included values which were invalid ... that would mean that the extracted file would also be invalid. 

IOW, it is not possible to get back the information that isn't there.
