Live Pack installation fails with error message 'Primary key must be unique'

  • Live Versions: Live 8.0 - 8.3.4
  • Operating System: OS X


When installing a Live Pack, the installation fails. The error message 'Primary key must be unique' appears.


It seems to be caused by the Migration Assistant on OS X.


Delete the Preferences.cfg file from

  • /Users/Library/Preferences/Ableton/Live 8.x.x

and the contents from these two folders

  • /Users/Library/Application Support/Ableton/Live 8.x.x/Database
  • /Users/Library/Caches/Ableton/Cache/Web/
