Driver downloaded from the Crosshair VII Hero drivers download page.

Unpacking the zip file of the downloaded driver zip archive gives the following error:
"There are some data after the end of the payload data."
The installed driver doesn't work and is replaced by a microsoft-signed generic driver upon restart.

Sonic Studio III does not work and says:
"The current system is not supported, or the audio driver has not been properly installed. NOPKEY"

The same corrupted driver was uploaded to the Crosshair VI Hero drivers download page.
