I have a VB.Net program that I wrote that when I add the CrystalReportViewer to the designer and try to run the program, outside of the IDE, I get an InvalidOperationException and the program will not even open. When I remove the CrystalReportViewer from the designer the program runs just fine? What do I need to do to get my program to work with the viewer?
