Hi all

Following code (Example 1) work fine on Excel 2010/2013 x86, windows x64 but don't work on Excel 2010/2013 x86, windows x32:
```
public void RunExample()
{
// start excel and turn off msg boxes
Excel.Application excelApplication = new Excel.Application();
excelApplication.DisplayAlerts = false;

// add a new workbook
Excel.Workbook workBook = excelApplication.Workbooks.Add();
Excel.Worksheet workSheet = (Excel.Worksheet)workBook.Worksheets[1];

// draw back color and perform the BorderAround method
workSheet.Range("$B2:$B5").Interior.Color = ToDouble(Color.DarkGreen);
workSheet.Range("$B2:$B5").BorderAround(XlLineStyle.xlContinuous, XlBorderWeight.xlMedium, XlColorIndex.xlColorIndexAutomatic);

// draw back color and border the range explicitly
workSheet.Range("$D2:$D5").Interior.Color = ToDouble(Color.DarkGreen);
workSheet.Range("$D2:$D5").Borders[XlBordersIndex.xlInsideHorizontal].LineStyle = XlLineStyle.xlDouble;
workSheet.Range("$D2:$D5").Borders[XlBordersIndex.xlInsideHorizontal].Weight = 4;
workSheet.Range("$D2:$D5").Borders[XlBordersIndex.xlInsideHorizontal].Color = ToDouble(Color.Black);

workSheet.Cells[1, 1].Value = "We have 2 simple shapes created.";

decimal d1=(decimal) 1.0099;
decimal d2 = (decimal)10001;

try
{
// Error here:
workSheet.Cells[10, 2].Formula = string.Format("=*{0}*{1}", d1, d2);
}
catch (Exception e)
{

throw;
}


// save the book
string fileExtension = GetDefaultExtension(excelApplication);
string workbookFile = string.Format("{0}\\Example01{1}", _hostApplication.RootDirectory, fileExtension);
workBook.SaveAs(workbookFile);

// close excel and dispose reference
excelApplication.Quit();
excelApplication.Dispose();

// show dialog for the user(you!)
_hostApplication.ShowFinishDialog(null, workbookFile);
}
