Access Excel Tables without having Excel installed ?

Question

Hello,

I recently wrote a program that reads values out of a Excel Table and that computer had Excel installed.

Now I'm working on a computer where Excel is not installed and I got this error when I try to debug the program.

Die COM-Klassenfactory für die Komponente mit CLSID 
{00024500-0000-0000-C000-000000000046} konnte aufgrund 
des folgenden Fehlers nicht abgerufen werden: 80040154 
Klasse nicht registriert (Ausnahme von HRESULT: 0x80040154 
(REGDB_E_CLASSNOTREG)).

It's in German but I hope you can help me.

Info: I added 3 .dll files

-Microsoft.Vbe.Interop.dll

-Microsoft.Office.Interop.Excel.dll

-Office.dll

Have I to add an additional .dll file? Or is it impossible to work without Excel installed?
