LocalDB parent instance version invalid: MSSQL13E.LOCALDB

Question

I\'m unable to add a database on a developer machine. I\'m running win 10, visual studio 2015. I re-installed SQL server 2016 twice, last time with firewall disabled it all

Answer 1

I had the same problem for migrating from SQL LocalDb 2016 to 2017.

I simply changed the value of the ParentInstance key from MSSQL13E.LOCALDB to MSSQL14E.LOCALDB and it worked !

Ty for pointing me to the key HKEY_CURRENT_USER\SOFTWARE\Microsoft\Microsoft SQL Server\UserInstances
