    Hi @bccrosby,

    Thanks for writing in.

    You don't have to grant 1Password any permission, 1Password is being blocked by a third party, changing the permission won't help.

    You mentioned Malwarebytes, several customers confirmed in this thread that updating to Malwarebytes 4.1.0 has fixed the issue.

    Please check for an update and then try again with 1Password.

  • I upgraded Malwarebytes to v4.1.0.56 & closed all the internet browsers and tried the 1Password upgrade again. The upgrade failed with the same error.
    Then I rebooted my pc and downloaded the 1Password upgrade again and tried the upgrade again.
    The 1Password upgrade was successful.

    Thank you.
