# Crystal Report Viewer

The Crystal Report Viewer is the viewer used to display report output. Setting a viewer at the user level overrides the default viewer.

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.
