SOLVED: Problems installing KB3172614 – Error message – “The update is not applicable to your computer.” Posted on October 16, 2019October 16, 2019 by dpejic My environment is Windows 2012 R2 Server DC on which I can’t install KB3172614 because is needed for PAM Bastion trust domain. Command on Domain Controler netdom trust /? was not list parameter /enablePIMTrust which was needed. I first install April 2014 update KB 2919355 and after that, I can install KB3172614 update that solve this problem. Way 3: Check If a Prerequisite Update Is Missing There is another thing you should do which is to check if a prerequisite update is missing. According to Microsoft, some updates need a prerequisite update before they can be applied to a system. Or else, Windows Update Standalone Installer not applicable will appear. For instance, if the error message happens on Windows 8.1 or Windows Server 2012 R2, you have to install the April 2014 update KB 2919355 as a prerequisite and one or more pre-requisite servicing updates (KB 2919442 and KB 3173424). To check whether you have installed these prerequisite updates, you can run the following PowerShell command: get-hotfix KB3173424,KB2919355,KB2919442
