error - need more than 1 value to unpack on V-magine

edit

Hi.

I'm trying to install V-magine on Windows Server 2012 R2.

Actually, i god a "list index out of range" error first, but i sloved with [https://cloudbase.it/downloads/v-magi...113-signed.zip] (https://cloudbase.it/downloads/v-magi...113-signed.zip) this file.

but now, i got a "need more than 1 value to unpack" message after "Downloading Hyper-V Openstack component".

Of course i tried to re-download the v-magine installer, but nothing solved.

I need a help. Thanks.
