Duplicati no longer launching on Mac - database version?

Support
18

I finally got together with my son on whose computer this issue was occurring. We still can’t launch Duplicati. Here are the answers to your questions. Any suggestions on how to proceed?

  1. It is a different Mac than the one that had issues from before.
  2. On the mac, the main Duplicati app is automatically launched at startup.
  3. Have not tried to launch from the command line. I have not used the command line tool before. I would need to learn how to do that.
  4. There is an error file that gets created when you try to launch! Here it is:
    System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. —> System.Exception: A serious error occurred in Duplicati: System.Exception: Failed to create, open or upgrade the database.
