Giving your consumers immediate access to Crystal Reports Viewer XI is fast and easy. You can send the link to download the viewer to your consumer in an email or on the web page displaying the viewer. So let us say you email a sales report every week as an email attachment. In the body of that report place the link to http://www.businessobjects.com/products/reporting/crystalreports/viewer/en/download.asp with some text saying something to the effect of "If you cannot view this report, follow the instructions from this link to download the viewer."
This allows consumers to access the viewer enabling them to explore the report information interactively on their desktops both on and offline.
