You should do some config in your WORD 2007.
Here is the screen shot for your ref.
As I am using Traditional Chinese WORD 2007, there will be some Chinese characters. You still can figure out how to do the config, though.
One thing to note: it will take much more time to generate linkable pdf, especially when you are working on a large file.
