I added a reference to the Word Interop Assembly and wrote a page that opened a Word document so I could get at the contents. All was fine.

I then published the site to a server and the site won't run ... the error message is cannot load the Word Interop Assembly.

I don't understand - this assembly is in the GAC - surely this should be available on the server?

Whenever you add a reference normally, you don't have to do anything to the server ... what is going on?

Thanks for any help.
