On my dev machine I have a full office 2013 along with my vs2010.

On my customer's machine, we need to run office automation with excel. My customer bought excel (but not a full office), and office automation doesn't work (there's no Excel Application listed in Component Services).

How to fix that?

I'm sure it is something in Excel's options where I need to add something or whatever. I hope somebody can help. On my dev machine, it just came with office...
