LocalDB does not starts correctly for IIS worker process

Question

When I deployed MVC application on IIS then localDB databse is not starting correctly. Error message is as follows: Windows API call WaitForMultipleObjects returned error code: 575. Windows system error message is: {Application Error} The application was unable to start correctly (0x%lx). Click OK to close the application. Reported at line: 3621.

But the localDB is working fine with visual studio application and with sqlserver management studio. I already have restarted it and recreated it by command prompt to make it work. But nothing is working. The problem came when i re installed IIS in my machine. How can i fix this. Any help will be appreciated.

Simply delete all files in "C:\Users\MYUSERNAME\AppData\Local\Microsoft\Microsoft SQL Server Local DB\Instances\v11.0" folder. Give write permissions to v11.0 folder. If you can't create another instance give write permission to Instances folder.
