This problem can be a result of a bad installation of Office. The first thing you should try is uninstalling and reinstalling LabVIEW and the toolkit. However, if this does not work, you should uninstall Office. You must also go into the system registry and delete all files that reference Office such as WinWord. You may then reinstall and Word should open as expected.
