Symptom

Cause of error
We do not know why it went wrong, 1603 means "something is wrong somewhere".
Unfortunately, the installation program does not provide any additional information, but you must troubleshoot the installation of LocalDb separately.
Create a log file
On the USB stick look for installation of LocalDb, look for Components\Utility\SqlLocalDB_x64.msi
Copy Components\Utility\SqlLocalDB_x64.msi to a temp folder
Start a dose prompt as administrator and set the working directory to the same temp folder, in the dos-window
Run the command: msiexec / i SqlLocalDB_x64.msi /l*v install.log
Analysis
