the method sort of class range failed c# - excel

Question

I´m trying to sort a column using Microsoft.Office.Interop.Excel using c# and I'm getting a "the method sort of class range failed" error. The code are:

        Excel.Workbook theWorkbook = objApp.Workbooks.Open("D:/rank.xls", Type.Missing, Type.Missing, Type.Missing, Type.Missing,
            Type.Missing, Type.Missing, Type.Missing, Type.Missing,
            Type.Missing, Type.Missing, Type.Missing, Type.Missing,
            Type.Missing, Type.Missing); 
        Excel.Sheets sheets = theWorkbook.Sheets;
        Excel.Worksheet worksheet = (Excel.Worksheet)sheets.get_Item(2);

        Excel.Range oRng = worksheet.get_Range("E4", "E100");
        oRng.Activate();
        oRng.Cells.Select();

        oRng.Sort(Type.Missing, Excel.XlSortOrder.xlAscending,Type.Missing, Type.Missing,
        Excel.XlSortOrder.xlAscending, Type.Missing,Excel.XlSortOrder.xlAscending, Excel.XlYesNoGuess.xlNo,
        Type.Missing, Type.Missing, Excel.XlSortOrientation.xlSortColumns,Excel.XlSortMethod.xlPinYin, 
        Excel.XlSortDataOption.xlSortNormal,Excel.XlSortDataOption.xlSortNormal,
        Excel.XlSortDataOption.xlSortNormal);

        theWorkbook.Save();
        theWorkbook.Close();
        objApp.Quit();
        Marshal.ReleaseComObject(objApp);

Am I missing something?

The spreadsheet are not protected and doesn't have a password to open it (I've tried in a simple spreadsheet with one column and 30 rows and doesn't work either)

If anyone can help, I'll be very appreciated.

Thanks in advance.
