My program currently exports / saves an Excel sheet as a CSV file.
However,
new program requirements call for my exporting the file as a ZIPPED CSV
file.

Our thoughts are to use a zip DLL component if one is available. This
will
be used by a large number of users and there is no setup routine involved.

I've looked at Dynazip and Xceed. The former appears to require a 3rd
party
setup program and the latter requires .NET development. Are there any
other
options?
