weather watcher causes MS Office to attempt to add feature

Hi, whenever I start WW, or if it’s started and I right click on the taskbar icon and “options,” Microsoft Office 2000 Pro attempts to add a feature. I can’t tell what feature, and since I can’t find the disk, I can’t add the feature anyway. I’ve been using WW for years and I’ve never seen this before, and can’t think of why it would need anything from Office, but I’m hoping you can suggest a way around this? This is a new install on my mom’s PC, which is running XP, by the way, not something that has just started happening on an old install. Thanks.
