Answer 1

[Walter Roberson]

The material I find links the error to full disk drive, either directly on the drive being installed or uninstalled from, or on the drive where the Java runtime lives. Also matlab often saves archives of what is installed and that could fill up too. I do not know which directory is used on Windows; on Mac it is under the Download directory

Installation key

[Walter Roberson]

I do not think this is correct. Errors in installation keys show up with a different error message, not a crash in background merge hit exception.
