Still problems on Linux:
$ unzip ./bat_v1_rc3.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 ./bat_v1_rc3.zip or
./bat_v1_rc3.zip.zip, and cannot find ./bat_v1_rc3.zip.ZIP, period.
$ unzip --version
caution: both -n and -o specified; ignoring -o

Perhaps you might consider 7z or another version of zip; should save your time answering support queries. :-)
