Hi Kalyan Can you try this: 1. Stop all user instance processes of SQL Server running under your local account (open up task manager and look for sqlsrv.exe process and end it) 2. Delete all files in the %LOCALAPPDATA%\Microsoft\Microsoft SQL Server Data\SQLEXPRESS folder 3. F5 again If the above solution is helpful then accept the answer.
