Devexpress Xtra reports

Question

Hi all. 

I am new to c#.

I have included Devexpress Xtra reports in my project. they work very well within my developer machine even after running a setup. the challenge is, the reports generate an error message and fail to launch on the targeted machines. where could I have gone wrong.
 See sample below.

 RportsList report = new RportsList();

            ReportPrintTool tool = new ReportPrintTool(report);

            tool.ShowPreview();

Thanks.
