I have an ASP.NET 2.0 application that includes a ReportViewer control setup to view reports in local mode. As a prerequisite to installing this application on a server I install the Microsoft Report Viewer Component with SP1. For the most part everything works as expected. However, I'm trying to setup a demo laptop to run the same web application. The demo laptop is running Windows Vista. I expect that the demo should work because I am also using Windows Vista as my development machine. After installing all the components the application appears to work normally except for the report viewer control. When the control loads all I get is the report viewer toolbar with a lot of broken images for it's buttons (and no report). I know it's partially working because if I have a problem in the .rdl file the control will give me the correct error info. But with a valid .rdl file I get nothing. I've tried uninstalling the control and reinstalling it with no success. I've also installed a full copy of Visual Studio 2005 on the machine to try and satisfy the demo but it still doesn't work. Can anyone help me to debug this control so I can get it to work on this machine?
