Robert,

A good place to start would be if you could tell us the extension of the
file type you are trying to open.

I have Windows 98 Retail OEM 5/11/98.
Occasionally I can't open an email attachment and get
a "NCompass ActiveX Plug In" screen reading "the viewer
required to display this file is not installed.Re-run the
Microsoft Office Setup program to add the required viewer".
I have not installed Office and don't have the Setup
software.
What installation programme is required to solve this
problem?
