Can't open downloads.

[Marly G]

When I download and click to open the download, it always goes to Archive Manager and says: "An error occurred while loading the archive". And beneath that it would read:
Archive: /home/administrator/Downloads/PageRageSetup(2).exe
[/home/administrator/Downloads/PageRageSetup(2).exe]
  End-of-central-directory signature not found. Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive. In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
zipinfo: cannot find zipfile directory in one of /home/administrator/Downloads/PageRageSetup(2).exe or
          /home/administrator/Downloads/PageRageSetup(2).exe.zip, and cannot find /home/administrator/Downloads/PageRageSetup(2).exe.ZIP, period.

I can't download anything.

Is this even a Mailman issue? What are you trying to download? From where?
