Ouch! Using Word Interop server side is one of the worst (if not the worst) mistakes you can do. It is not scalable at all. I've seen so many cases where these kind of interop applications/integrations have taken down the servers. Whatever you're trying to achieve - please stop using Word Interop server side.

What you need to do is to look at Open Office XML SDK (Bing it or Google it). That SDK is a perfectly safe way to work with Office documents (but only the new format; docx, xlsx etc)
