The issue being discussed in this article is:
A black console window keeps popping up, attempting to start SQL LocalDB when starting the SI Client.
The following is the cause:
The hard disk has a sector size greater than 4 KB. The issue is explained here.
The following is the resolution:
1/ Run the Command Prompt with the Run as Administrator option.
One way to do this is to search on your taskbar for "command prompt" and then right-click on the program.
2/ Copy and paste the following string into the command prompt and click Enter on the keyboard.
fsutil fsinfo sectorinfo C:
3/ Look for the values of PhysicalBytesPerSectorForAtomicity and PhysicalBytesPerSectorForPerformance (shown in bytes).
If either of these two values is larger than 4096, download, unzip, and run the SetSectorSize.zip file.
This file will adjust registry entries to allow the SQL Server local database to run.
4/ Restart the machine and test. A restart is required. After the restart, repeat steps 1 and 2 and verify that each value is set to 4096.
