  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.
  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.

We don't have any data on the specific error message here. This leads me to the conclusion that a previous Plesk updated was not completed successfully. I suggest to rerun the update installation from the Linux console.

# plesk installer install-panel-updates
