MS16-100 fails to install

Hi. Installing MS16-100 on Win2012 and Win2012R2 fails, but installing KB3172729 from Windows Update has no problems. But even if I install it With WU it shows as missing/applicable in Bigfix.
Any advise on how to get this patch installed With Bigfix? I have even installed all batches in WU, but still this is reported as applicable.

Hi Narveg,

You need to deploy the latest servicing stack update before installing MS16-100. The KB to install is written as Important Note on the Fixlet’s description.

Let us know again, or open a PMR should you still encounter errors.

Thanks!

To install the Patch MS16-100 , you need to install the Prerequisite patch to get it Complete.
The patch is unspecified in bigfix.
317342401 3173424: Servicing stack update for Windows 8.1 and Windows Server 2012 R2 - Windows Server 2012 R2 - KB3173424 (x64) Unspecified Patches for Windows

That’s right, the prerequisite patch is not a security patch thus does not carry a MSRC severity level (i.e. Source Severity = Unspecified).

Thank You for your replies, I will test out

I deployed the KB3173424 patch on a few Win2012R2 servers, followed by a reboot (status succeeded). Then I deployed the MS16-100 to the same servers, which ends in Failed status.

From the logfile I can see following:

A bit confusing why it says Relevant, and a few Seconds later says Not Relevant. Any suggestions why it Fails?
