I installed Office `07 shortly after purchasing the AAO and everything worked fine for several month. Then one day I went to open a .doc file and got some kind of error (sorry don't remember what it was). So I figured I would uninstall then reinstall Office to fix but it did not. Office would not uninstall. I deleted everything related to Office I could find (files, registry) and tried to install but just keep getting an error message "Installation could not be completed".
