This executable has built-in capabilities for exchanging information with a Microsoft Excel application.
It has no capabilities , except those provided via its general purpose OLE capabilities, to interwork with any application belong to the Microsoft Office suite, nor to interwork with any other suppliers office suite.
I have, out of pure personal interest, downloaded/installed the Apache OpenOffice Suite and ported one of their demos (WriterDemo) to run on this executable. The ported demo is available for here.
I do not recommend one office suite over another.
The only reason that I have focused on the Microsoft Office suite is because I wanted to the executable to be of help to me in my employment, and my employer requires me to use the Microsoft Office suite.
