MS Word cannot link to Endnote on 1 PC without admin permissions

I have 5 users using XP on one PC ( Endnotes 10) that are trying to link Word 2003 to endnotes.  I can link each individual user profile by giving him\her admin rights but when another user logs in to their profile in XP the link doesn’t work. I dont want to give users admin rights (its a nono here).

  Is there a way to link all users who log into that same PC to have Endnotes linked to Word  without admin rights ??
