I'm the administrator and simply run the command:

 sqllocaldb start v11.0

Result:

 Start of LocalDB instance "v11.0" failed because of the following error:
 Error occurred during LocalDB instance startup: SQL Server process failed to sta
 rt.

Event viewer log Event ID: 528

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.

I tried another (user and administrator) accounts, there were no problems with them.

I uninstalled & reinstalled 2012 version of SQLLocalDB.msi but I had no luck. Do you have any idea & fix?
