Answer 1

Assuming you want to create or edit Excel Files, I recommend using the new Open XML SDK from Microsoft. Works better and is easier than Excel Interop.

Answer 2

This is the problem: "i should work it out without installing ms-office"

You cannot start Excel if not Excel is not installed (duh). What are you trying to do?
