I am checking the Chipset INF file from our download and it is a .ZIP file. When you say extract the driver do you mean the exe?
I am sorry I am having problems to understand your question so I appreciate if you can elaborate more.
Extract version 9 and version 10 side by side and you will see that the newer version 10 drivers are "non-injectable" using Microsoft DISM.
Extracting version 10.x appears to use some kind of fragmenting of the files into some compressed format that cannot be read or injected
Yes use WinRAR to unzip...unzipped files are not installable via DISM
