Error when exporting reports using MAPI

Question

We created a .NET class that wraps CR 2010 .NET Crystal Reports functions and made it COM visible. This class is used to create a COM object in a js script which in turn used to export reports to a PDF file with the destination MAPI.
It exports reports just fine without any errors however if prior to instantiation the exporting class we instantiate a class that has nothing to do with the Crystal Reports functions, our exporting object throws u201CExternal component has thrown an exception.u201D error when exporting. It appears that it has something to do with the SideBySide feature. I was wondering if somebody knows what causes this and if there is a way to fix this problem.
Thanks for your help!

Below are 2 procmon.exe outputs, the first when exporting works and the second when it doesnu2019t

Answer 1

I tried to run exporting code in a .net application and got the same error. I first created the COM object that causes the problem and then ran exporting CR functions. It works fine if I run the code without creating the COM object.
Below is the code I used.
            Type objClassType = Type.GetTypeFromProgID("ebms.main");
            object objMain = Activator.CreateInstance(objClassType);
            try
                object[] p = new object[4];
                p[0] = "C:\\ebms\\co1";
                p[1] = "C:\\ebms\\co1";
                p[2] = "Administrator";
                p[3] = "";
                objClassType.InvokeMember("LoginToCompany", System.Reflection.BindingFlags.InvokeMethod, null, objMain, p);
            catch (Exception ex)
            this.RPTDoc = new ReportDocument();
            this.RPTDoc.Load(@"C:\\Users\\Paul\\Desktop\\AR Customer List.rpt");
            PdfRtfWordFormatOptions pdfOpts = ExportOptions.CreatePdfRtfWordFormatOptions();
            MicrosoftMailDestinationOptions mailOpts = ExportOptions.CreateMicrosoftMailDestinationOptions();
            ExportOptions exportOpts = new ExportOptions();
            pdfOpts.UsePageRange = false;
            exportOpts.ExportFormatOptions = pdfOpts;
            mailOpts.MailMessage = "something";
            mailOpts.MailSubject = "something";
            mailOpts.MailToList = "emailaddress";
            exportOpts.ExportDestinationOptions = mailOpts;
            exportOpts.ExportDestinationType = ExportDestinationType.MicrosoftMail;
            exportOpts.ExportFormatType = ExportFormatType.PortableDocFormat;
            try
                this.RPTDoc.Export(exportOpts);
            catch (Exception ex)
                MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
