Type mismatch on CRVS2010 appl. after install Crystal Reports 2011

Question

Hi,
I've a Windows application built in VS2010 with Crystal Reports for VS2010 that exports a report to a PDF, Excel or Word file. The application runs fine, but after the installation of Crystal Reports 2011 I got the "Type mismatch" error when the ReportDocument.Export method is called:
System.Runtime.InteropServices.COMException (0x80004005): Type mismatch.
at CrystalDecisions.ReportAppServer.Controllers.ReportSourceClass.Export(ExportOptions pExportOptions, RequestContext pRequestContext)
at CrystalDecisioins.ReportSource.EromReportSourceBase.ExportToStream(ExportRequestContext reqContext)
at CrystalDecisions.CrystalReports.Engine.FormatEngine.ExportToStream(ExportRequestContext reqContext)
at CrystalDecisions.CrystalReports.Engine.FormatEngine.Export(ExportRequestContext reqContext)
at CrystalDecisions.CrystalReports.Engine.ReportDocument.Export(ExportOptions options)
at MyApp.ReportConfig.Execute() ....
HELP!!!!
Uninstalling Crystal Reports 2011 SP1, Crystal Reports 2011, Crystal Reports for Visual Studio 2010 SP1 and Crystal Reports for Visual Studio 2010 (in this order) followed by a re--install of Crystal Reports for Visual Studio 2010 and Crystal Reports for Visual Studio 2010 SP1 does not remove the problem.
Config:
Windows 7 Ultimate x64

Yes, I asked them to make note also, there have been delays, it was decide to hold off after the info was released and by then it was too late. Once it gets out everyone seems to be able to get it....
So are you having problems installing still or just exporting? If exporting what code are you using?
Have you set your Project for 32 or 64 bit, not anycpu?
What framework are you using, Any of the FULL versions is a must.
Try this sample:
        private void ExportToStream_Click(object sender, EventArgs e)
            CrystalDecisions.Shared.MicrosoftMailDestinationOptions mailOpts = CrystalDecisions.Shared.ExportOptions.CreateMicrosoftMailDestinationOptions();
            CrystalDecisions.Shared.DiskFileDestinationOptions diskOpts = CrystalDecisions.Shared.ExportOptions.CreateDiskFileDestinationOptions();
            CrystalDecisions.Shared.ExportOptions exportOpts = new CrystalDecisions.Shared.ExportOptions();
            CrystalDecisions.Shared.CharacterSeparatedValuesFormatOptions csvExpOpts = new CrystalDecisions.Shared.CharacterSeparatedValuesFormatOptions();
            CrystalDecisions.Shared.HTMLFormatOptions HTMLExpOpts = new CrystalDecisions.Shared.HTMLFormatOptions();
            rpt.Load(@"c:\reports\b.rpt");
            diskOpts.DiskFileName = @"c:\reports\worldsales.pdf";
            exportOpts.ExportDestinationType = CrystalDecisions.Shared.ExportDestinationType.DiskFile;
            exportOpts.ExportFormatType = CrystalDecisions.Shared.ExportFormatType.HTML32;
            exportOpts.ExportDestinationOptions = diskOpts;
            HTMLExpOpts = new HTMLFormatOptions();
            HTMLExpOpts.HTMLEnableSeparatedPages = false;
            HTMLExpOpts.UsePageRange = false;
            HTMLExpOpts.HTMLHasPageNavigator = false;
            System.IO.Stream oStream;
            byte[] byteArray = null;
            oStream = rpt.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);
            byteArray = new byte[oStream.Length];
            oStream.Read(byteArray, 0, Convert.ToInt32(oStream.Length - 1));
            // this is used to verify the file so I saved it to disk
            System.IO.File.Create(diskOpts.DiskFileName, Convert.ToInt32(oStream.Length - 1)).Close();
            System.IO.File.OpenWrite(diskOpts.DiskFileName).Write(byteArray, 0, Convert.ToInt32(oStream.Length - 1));
            System.IO.File.SetAttributes(diskOpts.DiskFileName, System.IO.FileAttributes.Directory);
            oStream.Close();
            GC.Collect();
            MessageBox.Show("Export to Stream complete", "RAS", MessageBoxButtons.OK, MessageBoxIcon.Information);
