I almost wasted my whole day trying to install Windows Azure Storage Emulator but somehow it is not getting installed..
The log is showing me this error : Sql instan
For those who has new Azure Storage Emulator 4.5 and SQL Server 2016. As MWood mentioned, check c:\users[UserProfile] directory and delete any AzureStorage* databases found.
Then open command window and write same commands, but change database to V13 (the number depends on the SQL server database version installed on your machine).
sqllocaldb stop v13.0
sqllocaldb delete v13.0
sqllocaldb create v13.0
Then install Azure SDK tools again.
