I receive the error "Failed to detect the installation setup requirements (code: -5)" when I install the Outlook Connector.

If you receive the error Failed to detect the installation setup requirements (code: -5) when installing the Outlook Connector, you may be running Outlook 2000 in "Internet only" mode. To fix this, re-enable Groupware mode.

  1. Open the Tools menu, and select Options > Mail Services > Reconfigure Mail Support. Choose either "Corporate" or "Workgroups".
  2. Close Outlook.

You should now be able to install Kerio Outlook Connector.
