问题 Is it possible to upgrade SqlServer localDB from 2012 to 2014? We currently use version 11 from SQL Server 2012. I need to upgrade to version 12 from SQL Server 2014.

问题 I am getting Windows API Call Error Code : 0 I have installed SSMS 2018 and was trying to find out if I have any other versions installed.
