SharePoint 2013 Missing Patches – Configuration Wizard error

​I recently ran into some issues applying KBs on a SharePoint 2013 farm. My farm consists of 6 servers:

1. 2 WFE servers;
2. 2 Application servers (hosting Central Admin); and
3. 2 Search servers

As usual, I installed all the KBs on all servers first, starting with the application server, then I started running the SharePoint Configuration Wizard on all the servers. The wizard successfully completed on the 2 Application Servers, but failed on the rest of the servers.

The error I was getting was:

“Error: Some farm products and patches were not detected on this or other servers. If products or patches are missing locally, you must quit this program and install the required products and patches on this server before starting this wizard. If products or patches are missing on your servers, you must install the required products and patches on the specific servers, and you may then click the Refresh button to perform the status check again.”

I have tried rebooting the servers and running the psconfig -cmd installcheck -noinstallcheck, but this did not help. I was getting the same error through the script. The farm thinks that the servers did not get the required KBs.

After further investigation, it turns out that the application registry on the servers needed to get refreshed. I ran the following PS command (as administrator):

Get-SPProduct –local

This will force a refresh of the server. You will need to run the command on all of the affected servers before you can run the configuration wizard again.
