Lack of support implies that no new security patches for the product
will be released by the vendor. As a result, it is likely to contain
security vulnerabilities.

Note that Excel Viewer was formerly known as Excel Viewer 2007. The
file versions are the same, only the name has changed in references
to the product.");
