Thread: Porting VSTO Excel program from Office 07 to 03

Hi all,

I made an application modifying Excel files referencing v12 COM component with Office 2007 and now I want to make a compatiable version for Office 2003.

I removed the v12 reference to Office & Excel, copied to another PC (with Office 2003) and referenced v11 Excel & Office COM objects.

Problem is it tells me that Microsoft.Office.Interop.Excel.Range isnt a valid reference anymore! Is there anything else I need to change to make this compatiable?

Thanks for any help,
Alex Webb
