Open an excel application with .NET

[ysommer]

Hi,
I'm Trying to open a excel workbook in c# I add a refernce
in my project to Microsoft Excel Object 10.0.
and I write this code:

Excel.Application oExcel = new Excel.Application();
oExcel.Visible = true;
Excel.Workbook oBook = oExcel.Workbooks.Add(Excel.XlWBATemplate.xlWBATWorksheet);

But I always get the exception "Old Format or Invalid Type Libary"
I cant figure out whats the problem,
Any sugesstions?

Thanks,
Yoel
