C# .Net 2005 to Excel 2003 - interop problem

Hi guys,

Iam interacting with Excel 2003 through C#, using interop:

using Office = Microsoft.Office.Core;

using VBIDE = Microsoft.Vbe.Interop;

using Excel = Microsoft.Office.Interop.Excel;

It works fine on my pc (with VS.Net 2005 and full Excel 2003), but when I try tu run it in an other pc (with just .Net framework and limited version of Excel 2003) it gives me an error.

It think there is some missing file (for Excel interop), and I need to run the program with Excel 2003, and also XP.

Does anyone knows what should I do

Thanks in advance,

Aldo.
