Failed to load database information.

Hello...

I am using:

Window Server 2012 64bit

VS 2012

ASP.NET 4.5

Crystal Support Pack 8

I have pretty simple code below.  Just take DS Table merger with .RPT file and generate a PDF.

Works fantastic when run in VS in Debug.

But crashes when run through IIS via browser (Failed to load database information).

I attached the full error stream below my code.

Please help, no idea what's wrong...

CODE:

---------------------------------------------------------------------------

        public void reportPdf(DataSet DS, string rptFileName, string reportDsName)

        {

            ReportDocument crystalReport = new ReportDocument();

            crystalReport.Load(System.Web.HttpContext.Current.Server.MapPath("~/Crystal/" + rptFileName));

            crystalReport.SetDataSource(DS.Tables[0]);

            //crystalReport.ExportToStream(ExportFormatType.PortableDocFormat);

            HttpContext.Current.Response.Clear();

            HttpContext.Current.Response.ClearContent();

            HttpContext.Current.Response.ClearHeaders();

            HttpContext.Current.Response.ContentType = @"application/pdf";

            HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=Report.pdf");

            HttpContext.Current.Response.Charset = "utf-8";

            HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("windows-1250");

            crystalReport.ExportToHttpResponse(ExportFormatType.PortableDocFormat, HttpContext.Current.Response, false, "");

            // HttpContext.Current.Response.BinaryWrite(bytes);

            HttpContext.Current.Response.Flush();

            HttpContext.Current.Response.End();       

        }
