The issues is resolved. In the web.config file I placed the following:
<configSections>
...
...
</configSections>
<businessObjectts>
<crystalReports>
<rptBuildProvider>
<add embedRptInResource="true"/>
</rptBuildProvider>
<crystalReportViewer>
<add key="ResourceUri" value="/crystalreportviewers13"/>
</crystalReportViewer>
</crystalReports>
</businessObjects>
The issue was caused because the folder "crystalreportviewrs13" is part of my project and if you look above the line '<add key="ResourceUri"' is pointing to an absolute url and it needs to be virtual. So the correct line should be as follows:
<add key="ResoureUri" value="crystalreportviewers13"
Thank you for you help. It did make me look back at my web.config file a little harder.
