Code for 7.1 is in box.
Registered S/N on Razer ID.
(At this point I must mention I have Synapse 2.0 installed because I own/use Mamba and BW Chroma X.)
Download latest(1.0.1.12 / 90MB) 7.1 from the Kraken X USB support page.
Run as Admin on installer.

I click 'Install.
It downloads then Installs.

I click 'Get Started' without unchecking 'Launch 7.1 Surround Sound.'
New Razer Green themed icon appears in Task Bar




At this point, I have tried logging in with both the right click and left click on previous attempts.
This time I close (R-Click>Exit), then Launch again from the shortcut that was created on my Desktop without my asking (Please ask first to clutter my Desktop)(Also, please ask where to install, even if it requires an extra step or three).

New/Same Razer Green themed icon in taskbar

Left Click Icon presents this window
Can't include anymore step-shots here... limited to 10.
