The release note states: ‘The v4 version prevents installation of the COP file on 12.5 SU1 as exports done on 12.5.1 SU1 will likely cause the “Fresh Install with Data Import” to fail.’ This means it cannot be installed on 12.5.1 SU1. Are you on SU1? If you are on another SU, this should work. If you are on SU5, there is no need to install it as the commands are natively available.
Versions v3 and lower are not available for download. If you are on SU1, you need to reach out to Cisco TAC. They might be able to help you, but you will likely need to move to another SU. According to the release note, data exported from SU1 can cause failures when performing a fresh install with data export. And that’s why it’s preventing the installation on 12.5.1 SU1.
