fail to import sandbox into virtual box

Hello, I tried many times to import ‘Hortonwork sandbox’ from my Desktop to Oracle Virtual Box 5.0.2

There’re error messages as below:

Failed to import appliance <b>C:/Users/Admin/Desktop/program/Sandbox_HDP_2.3_1_virtualbox.ova</b>.

Could not create the imported medium <b>’C:\Users\Admin\VirtualBox VMs\Hortonworks Sandbox with HDP 2.3\Hortonworks Sandbox with HDP 2.3-disk1.vmdk'</b>.

VMDK: Compressed image is corrupted <b>’C:\Users\Admin\Hortonworks Sandbox with HDP 2.3-disk1.vmdk'</b> (VERR_ZIP_CORRUPTED).

</tr>
</tbody>
</table>
 

I don’t know why it happened ?

I use Window 8.1 and install Virtual box 5.0.2

I allocated RAM 4 GB and CPU 2 cores.

Please help .

Thank you
