Crystal Reports Unable to Cast COM Object of Type ‘ReportSourceClass’ to Interface Type ‘ISCRReportSource’

When creating or printing a report using Crystal Reports, including printing reports to printer or generating reports in Acrobat PDF format, the following error on Crystal Report Windows Forms Viewer may occur and no report is generated or created.

System.InvalidCastException: Unable to cast COM object of type 'CrystalDecisions.ReportAppServer.Controllers.ReportSourceClass' to interface type 'CrystalDecisions.ReportAppServer.Controllers.ISCRReportSource'. This operation failed 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)).

The error normally happens due to incompatibility between different version of Crystal Reports or normally occurs after platform updates.

Thus, to resolve the “Unable to cast COM object of type ‘CrystalDecisions.ReportAppServer.Controllers.ReportSourceClass’ to interface type ‘CrystalDecisions.ReportAppServer.Controllers.ISCRReportSource'” issue, make sure to remove all old Crystal Reports assemblies from Reference list in all projects. Then add new Crystal Reports assemblies and rebuild the application. If you’re unable to rebuild the app, add the following code in app.config/web.config to make sure <dependentAssembly> workaround as suggested by SAP:

Replace the values for newVersion and oldVersion accordingly based on your deployment version.

If the Crystal Reports error only happens on some computers, but not on others, make to to update and deploy same versions of Crystal Reports to all workstations.
