If problems occur during uninstall, also consider the notes in chapter Problems with WebOffice extensions Uninstall.

If you have installed WebOffice extensions with ArcGIS Engine, it will also be uninstalled during the uninstall process of the WebOffice extensions. To avoid problems during the uninstall/install process, please ensure in that case, that the ArcGIS Engine still exists on the system before uninstalling the WebOffice extensions.

If GeoOffice is installed next to WebOffice 10.9 R4, you must make sure that outdated GeoOffice modules are updated or, if no longer needed, uninstalled. Otherwise you may experience problems when using WebOffice 10.9 R4.
