Answer 1

I just came across this thread when I had the same error from a PowerShell script calling the Net.WebClient DownloadFile method.

In my case, the problem was that the web server was unable to provide the requested zip file, and instead provided an HTML page with an error message in it, which obviously could not be unzipped.

So instead, I created an exception handler to extract and present the "real" error message.
