Crystal Reports Not Working in Web Application: COMException (0x8007007F)

183 Views

Hello,

I am currently working on upgrading an ASP.NET web application to use Crystal Reports SP31. When running the web application on our web server, I get the following error:

System.Runtime.InteropServices.COMException (0x8007007F): Retrieving the COM class factory for component with CLSID {F734A321-8381-4FFD-A614-139E8906DC83} failed due to the following error: 8007007f The specified procedure could not be found. (Exception from HRESULT: 0x8007007F).

at CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper.CreateRptDoc()

at CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper..ctor()

at CrystalDecisions.CrystalReports.Engine.ReportDocument.Initialize()

at CrystalDecisions.CrystalReports.Engine.ReportDocument..ctor()

at CrystalDecisions.CrystalReports.Engine.ReportClass..ctor()

The Crystal Reports runtime (32-bit) is installed on the web server, and its IIS is configured to allow 32-bit applications. I've run the same web application on my own local machine with no problems.Any advice would be greatly appreciated.
