Visual Studio Tools for Office Setup Problem and Fix
I'll place this here for the benefit of others:
I just installed Visual Studio Tools for Office, and everything seemed fine. However, when I created the first Word Template project, it couldn't find the reference to hte Microsoft.Office.Core namespace. Half an hour of searching the web and I came across a fix that worked for me: insert the Office 2003 CD into the disc drive, and select the Repair installation option. Re-open the project, and Visual Studio should be able to find the reference.
