how did you downloaded "this package".
My suggestion: Download 4GB zip file using Download Manager and unzip it using 7-zip software.
Info concerning Download Manager:
To take advantage of Download Manager, you have to:
- install Java Java SE Runtime Environment ... in my case it is Java SE Runtime Environment 8u60
- use Firefox browser to download zip file ... in my case it is Firefox 40.0.3
Download Manager can by launched from Firefox, only. It does not work in combination with Internet Explorer an Chrome.
