.dll file not accessible

Question

I am trying to add a dll to my project. When I do "add reference" and try to add it, it tells me :

"A reference to ... could not be added. please make sure that the file in accessible, and that it is a valid assembly or COM component".

BTW, I am trying to add g729.dll

How can I add the dll?
