In Germany I have developt an application with VB.Net (1.1) and C# (1.1) with
Excel (Microsoft.Office.Interop.Excel). This application worked very well
with Excel 2000, XP and 2003.

Now I'm in Litvia. And the same application with Excel XP give a strange
exception:
Old format or invalid type library.

I don't understand, my my programm don't work:
Dim WithEvents EAppl As Application = New Application
Dim wbs As Workbooks = EAppl.Workbooks
EAppl.Visible = True
wbs.Open("Book1.xls")
....

Thank you
