There could be a couple of things at play here.
First, is the macro saved with the document? Meaning is it sent with the document or is it saved as a local macro?
Second, is everyone else's trust center setup to allow macros?
If you would like, the 2014 EPDM training files include a couple of word documents that have this macro stored inside them. It should be easy to download the training files from the SolidWorks website and review these files.
