R6700v3 Firmware Version 1.0.4.92 - Hot Fix

I got the email about the security advisory. I logged into my router and it says that there are no new firmware versions. I have version V1.0.4.84_10.0.58. I logged into my account on Netgear's website, I dowloaded R6700v3 Firmware Version 1.0.4.92 - Hot Fix. But now I don't know what to do with the download, it's a zip file. It says to click on the link provided for instructions on how to do it, but it takes me to my product's page, but nothing comes up when I click downloads or documents. There is absolutely no help. I found a user manual through Amazon but it's not really helpful because it only tells me how to log into the router and check for updates, which I already did. I'm using a Windows 10 laptop. Can anyone please help, I would  really appreciate it!
