Problem running deepstream-test3 with IP camera

Hi,
when I run

unzip R32_2_DS_4_0_PREBUILT_LIB.zip

I got this

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 R32_2_DS_4_0_PREBUILT_LIB.zip or
        R32_2_DS_4_0_PREBUILT_LIB.zip.zip, and cannot find R32_2_DS_4_0_PREBUILT_LIB.zip.ZIP, period.

It seems the zip is broken?
Can you reupload it please? Thanks
