Microsoft Office is optional. If you install Office after installing Historian Client,
the Historian Client add-ins do not appear in the list of Office add-ins. Run the
Historian Client installation program and repair the installation to load the Office
add-ins.
When you perform a custom installation of Microsoft Office (32-bit), you must install
Office Shared Features and Office Tools so that the Historian add-ins for Workbook
or Report can be loaded.
Note: Make sure that you are not using the 64-bit version of Microsoft Office.
