Seeing this in your Error Logs now that ESET is installed?
"SQL Server Native Client 11.0: Unable to load sqlnclir11.rll due to either missing file or version mismatch. The application cannot continue."
Install this to patch to the SQL Server Native Client 11.0 to the latest patched version (11.4.7462.6) which at the time of writing this, has a valid certificate for sqlnclir11.rll.

If you have SQL Server 2012 installed, it will try and patch that in addition to the Native Client. There is still the option to choose to only patch the Native Client. The other option is to stop something that ESET is scanning, but why when you can make it work!
