intertwingly

I’ve downloaded the multi-part zip archive for IE11 on Win10 for VirtualBox on OS/X from modern.ie.  I’ve downloaded the single-file archive on both OS/X and Linux.  I’ve verified the md5 signatures for each.  Yet each time, when I try to unzip the result, I get the following:

$ unzip IE11.Win10.For.LinuxVirtualBox.zip
Archive:  IE11.Win10.For.LinuxVirtualBox.zip
warning [IE11.Win10.For.LinuxVirtualBox.zip]:  4294967296 extra bytes at beginning or within zipfile
  (attempting to process anyway)
file #1:  bad zipfile offset (local header sig):  4294967296
  (attempting to re-compensate)
  inflating: IE11 - Win10.ova        
  error:  invalid compressed data to inflate

I’ve even tried jar xf with no luck:

$ jar xf IE11.Win10.For.LinuxVirtualBox.zip
java.util.zip.ZipException: invalid entry size (expected 5632888297048912 but got 4801961472 bytes)

This shows signs of integer overflow, so it seems likely that the problem is client side.  Even with that said, choosing to make a this content available in a format for which there isn’t working client libraries available to unpack it isn’t helpful.
