Hi we're using XlsIO and we have this error when trying of open a file in a route with this code:

string ruta2 = HttpContext.Current.Server.MapPath("~\\Reportes\\Masters\\MasterIncidenciaEnfermedades2.xlsx");
ExcelEngine engine = new ExcelEngine();
IWorkbook libro = engine.Excel.Workbooks.Open(ruta2);
IWorksheet hoja = engine.Excel.Worksheets[0];

When open the route appear this error: "Ya existe una entrada con la misma clave."

Hi Roimer, 

Thanks for contacting Syncfusion support. 

We tried all possible scenarios to recreate the stated exception “Ya existe una entrada con la misma clave.”(English translation: There is already an entry with the same key) in our end but we were not able to reproduce the exception. We kindly request you share the input document upon which you faced the mentioned exception.

Hi, the problem occurr with the file attached to this forum (FileError.xlsx).

We thought it may be because it has a graphic that need create starting of information that put in the table in the sheet1 "Informacion".

We are needing that the graphic appear how the example attached too to this forum (Example.xlsx)
