About this task
Both the Historian Administrator and Historian HDA Server are installed by default when you install the Client Tools. It is recommended that you keep the default selections when you are installing Client Tools, because if you deselect them during the initial Client Tools installation, and then go back to install them, any check box that you deselect during the second install will uninstall the deselected component. Note: If you choose to install the HDA server at a later time, make sure that Historian Administrator is installed before you install the HDA server, or select them together in the Select Features screen.
You can install the Historian OPC HDA Server on any server on which the Historian Server has been installed.
