# Default Crystal Report Viewer

The Default Crystal Report Viewer is the viewer used to display report output when the viewer has not been overridden at the user level.

The viewers have different capabilities. The most widely used viewers are the HTML and ActiveX. HTML is the most basic viewer and does not include advanced printing or the ability to export to other formats. The ActiveX viewer installs a control on each client machine and is the closest to providing the same functionality found in the Crystal Report Designer.
