Unable to cast object of type 'Microsoft.ReportingServices.ReportRendering.Calendars' to type 'System.String'. RRS feed

  • Question

  • My old CRM 4.0 was on a Windows 2003, 32 bit, platform with SQL Server 2005 installed.  Recently, I installed CRM 4.0 on a Windows 2008 R2, 64 bit platform with SQL Server 2008.  I also copied over and attached old database MSCRM, in mdf and .ldf, to the new server and installed CRM 4.0 rollup 1 - 8 on the new Windows 2008 R2 server.  However, the problem came from the report.  When I tried to run report in CRM Reports section, such as Quote, Order, etc, it cames with this error: Unable to cast object of type 'Microsoft.ReportingServices.ReportRendering.Calendars' to type 'System.String'.  I have tried many approaches and feel like I starts to be scrambling.  Any thoughts?  It seems to have nothing with the Report Services, because I only run report in Reportviewer.
