Surveillance download and install problem RN31211D Firmware 6.4.2

Before I ask my questions on my installation issues, I saw this thread and have a related question:

http://community.netgear.com/t5/Current-NETGEAR-and-Partners/Unable-to-install-Surveillance/m-p/1045940#M4518

Am I understanging this thread correctly, that Surveillance can't be installed or maybe can't be activated at this time because of the vulnerability issue?

---------------------

Here is my question with regard to installing Surveillance on my 312 boxes (I have 2 boxes)  RN31211D Firmware 6.4.2.

The manual (link below) on p8 states that for OS 6 navigate to Apps then Installed Apps. When I do that there are no installed apps listed. http://www.downloads.netgear.com/files/GDC/RNNVR01L-1000S/Surveillance_UM_31March14.pdf

So then I searched the community posts and found the thread -- first link in this post above. That thread conatains this link: 

http://kb.netgear.com/app/answers/detail/a_id/30275

which contains a link for this Surveillance download package:

http://apt.readynas.com/packages/readynasos/dists/apps/pool/s/surveillance/surveillance_1.4.1-3_amd64.deb

I downloaded the package to my PC, then ran the app upload function (Upload icon on the RN312 Apps page) and got the error message "Cannot install application C:/.../surveillance_1.4.1-3_amd64.deb"

Does anyone know what I might be doing wrong? Or can anyone offer another way to get Surveillance installed?

Thanks
