I am trying to patch one node in a SQL Server 2016 Standard FCI. I removed the node from the cluster, and ran the installer, but it failed.
The summary file contained the following exit code / message:
Exit code (Decimal): -2146233079 Exit facility code: 19 Exit error code: 5385 Exit message: The given key was not present in the dictionary.
I cannot find anything obvious in the "Detail" file.
Can anyone recommend where I could go to get a clearer idea of what failed?
