Kindly help me regarding our issue with a Clustered Environment's applied patch.
The situation is: We removed a SQL Patch: GDR 6248 for SQL Server 2012 (KB3194721) (64 bit). When we successfully removed the patch on the first node, we rebooted it. Now when we tried to remove it on the second node, we can't proceed to uninstall the patch as there are missing files.
We attempted to remove the patch again using some ready
msi files on our repository. We successfully removed the patch. SQL Management Studio detects the correct service pack, which is SP3.
The issue now is on the OS where the patch we're trying to remove is still on the View Installed Updates List. Please advise how to remove it? What steps to take that is least harmful to the clustered setup?
OS Version: Windows Server Enterprise 2012
Database Version: SQL Server 2012 SP3
