Archive:  amd-catalyst-13.12-linux-x86.x86_64.zip

  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.

unzip:  cannot find zipfile directory in one of amd-catalyst-13.12-linux-x86.x86_64.zip or

        amd-catalyst-13.12-linux-x86.x86_64.zip.zip, and cannot find amd-catalyst-13.12-linux-x86.x86_64.zip.ZIP, period.
