About Installing Historian Components

After you have installed the Historian server and restarted your system, you can install additional components, such as Client Tools, the Historian Excel add-in, the Web-based Clients, data collectors, and Historian Alarms and Events.

Historian Administrator and the OPC Classic HDA server are installed as part of the Client Tools installation.
Note: On a 64-bit Windows operating system, the default destination folder for all 32-bit components (such as collectors and APIs) is C:\Program Files\Historian\x86. Similarly, for all 64-bit components (such as Excel Add-in 64-bit and SQL Server 64-bit), the default destination folder is C:\Program Files\Historian\x64.
