Found a user's machine where whenever they opened any Office document IE crashed. This seemed to work:
(not specifically Word) Resolution: Step 1) Close all Internet Explorer and Office programs/windows Step 2) Delete this file: C:\Program Files\Microsoft Office\Office 12\OWSSUPP.DLL Step 3) Run the Microsoft Office Diagnostic located in Start --> Programs --> Microsoft Office --> Microsoft Office Tools --> Microsoft Office Diagnostic
Step 4) It should find 1 error and have fixed it. Now you can open your programs back up and try the SharePoint site. This should fix the problem.
