Symptom: every time you start Word reconfiguration starts up. If you start Word in Safe Mode (by pressing Ctrl while launching application) it starts normally.
Note: I've installed Office 2010 after removing a previous Office 2007 installation.
Comment: this is a very popular subject on the internet. I confess I've tried the NoReReg solution and Microsoft Fix uninstall without success before trying this simple solution.
Cause: The previous installation had COM addins that where not removed from the registry by the uninstall process, even by the Microsoft Fix uninstaller.
Solution: Launch Word, and once it has configured in File\Options\Addons(components) disable all components.
This was quite an overlook, but i post it as a reminder.
