Vista - Word 2003/Vista/MedRemote not finding Word

I have a Lenovo laptop which my husband purchased for my daughter. It came with the Vista bundle and recently he downloaded Microsoft Office Suite 2003. The laptop is set up with different users, specifically my husband as the administrator, myself with administrative authority, and my daughter with no privileges. I work as a medical transcriptionist and am planning on using the laptop when I go on trips. I downloaded Nuance MedRemote Webtop. This program has 3 components: one component with the patient demographic information, an audio player to listen to the digital voice recordings, and then a Word program. It can work with Word 2000, 2003, or 2007. I have MedRemote loaded on my main computer with Word 2000 on an XP platform and it works fine. On the laptop, however, the MedRemote cannot find the Word program. It gives me an error "Word not available." However, I do have Word 2003 and it works fine. I have run the detect and repair option on Word 2003 in the hopes that this would help, but it did not. It may be that MedRemote is not finding the "normal.dot" page. Can anyone help with this? I really appreciate it!
