c# - Is there a way to automate MS Office applications without license? -

i writing application perform automation in excel. have ms office (2007) installed on work computer , application working fine referencing the microsoft excel 12.0 object lirary.

the target machine has office installed not registered. 1 of preinstalled editions. attempting run application on target machine error saying office not installed?

i'm assuming have have registed office use object libraries? there anyway around not have office license key lying around , quite expensive?

see if can run excel manually on machine. if can this, should able automate well. if cannot, don't expect able somehow miraculously (and legally) make work through automation. automating office through object library no different using through ui. need have licensed , installed copy of office in order able use it.
