    I've just enjoyed creating about 30 telerik reports for a demo tomorrow, and I though slapping a ReportViewer onto a web page and getting on with serious challenges was my next mission, but it turns out the most urgent challenge is getting the ReportViewer to work.

    I have a clean web site project, with only one page, and only bin references to telerik reporting.  In my bin I have Telerik.Reporting.dll, Telerik.Reporting.Processing.dll, Telerik.ReportViewer.WebForms.dll, and Telerik.Web.UI.dll (as a control lib).  The RadControl on the same page works when I remove the ReportViewer, but as soon as the viewer is on the page, I only get Failed to map the path '/'.  My web page has no code, the whole web site project is clean and new, and all defaults.

    Any ideas as to why this is happening?

    Hi ManniAT,

    This error is usually caused by combination of Vista/Win7, VS2008 not running as administrator and using the default Cassini web server. Closing VS2008 and starting it as administrator should resolve the problem.

    Kind regards,

    I just encountered this same error and running it as administrator worked. Is there going to be a fix for this? I don't want to have to run Visual Studio as Administrator any time I am working with a Report Viewer?
