Dax unsigned, win 7 update not working, KB3004394 dubious, dead in the water

  • Updated 4 years ago
I have not read all 4,172 responses to "DAX unsigned..."
I have filed a support ticket. No joy yet.
I have installed KB3004394 and waited 36 hours (48 actually).
I have doubts if KB3004394 actually works per http://borncity.com/win/2014/12/10/update-kb3004394-breaks-root-certificate-in-windows-7-windows-server-2008-r2/
I have tried to update my root certificate using Windows update, but as of 3 days ago, Win update just runs forever without showing any progress.
I have uninstalled, re-installed SSDR and rebooted until I got blisters on my fingers.
I could not load screen shot here ;-(

If there is anyone out there who has overcome the "DAX unsigned" problem and is actually running DAX please help me. Maybe send me a list of all Win 7 updates you have installed?

Trying to run Win 7 HP, Flex 6300, SSDR

I too had the same problem as you on a much out of update computer.  It took 48 hours of running Windows updates and over 350 different patches to get the computer up to date.  I just left it running to see if it would ever finish - much to my surprise it did.

Alas, the only other solution I could suggest would be to upgrade the computer to Windows 10.

The problem is not that the drivers are unsigned but that the out of date version of Windows 7 does not include Microsoft's new root certificate that was used to sign the certificate they issued to FlexRadio.

I wish I had better news for you.

I went through the same nightmare with Windows updates. There is a solution.

I had your exact problem with win7 and SmartSDR V1.6.21 I submitted a ticket, did everything they said to do, and made sure that I had all of the updates for win7, waited a day, then ran that kbxxx file that support pointed me to, and low and behold, the certificates did update, and I was all set. You have to just let windows update contintue to churn, overnight if need be, and be patient. that worked for me. Keith W7ZAC

Thanks to all responders.  The point that I missed was that the computer needs to run uninterrupted for hours.  My 225 updates took a mere 8.7 hours plus restart, wait, restart, etc.
I can hardly wait to be pushed and shoved into win 10!
