I have a program created with WPF and Entity Framework and Crystal Report. In my computer, everything runs correctly, but in the client computer I have a problem when I want to use the reports. I used the CrystalReportsViewer for WPF to display the report and added all the DLLs to the references, and I installed Crystal Report Runtime on the client computer. But there is an error while running the report in the computer.
Error:
Unable to cast COM object of type
'CrystalDecisions.ReportAppServer.Controllers.ReportSourceClass' to interface
type 'CrystalDecisions.ReportAppServer.Controllers.ISCRReportSource'.
This operation faild because the QueryInterface call on the COM component for
the interface with IID '{98CDE168-C1BF-4179-BE4C-F2CFA7CB8398}' failed due to
the following error:No such interface supported (Exception from ?
HRESULT:0x80004002(E_NOINTERFACE)).
