Note for 2010 users

Should you get the idea, their existing Office 2010 to expand a module from the series 2013: Forget it. Supposedly it works. All attempts to accomplish this led me to crashes / error messages.
If you want to replace by 2010 2013: It has essentially changed the design. Content there are no differences which would justify the initial purchase at that price. The uninstallation of Office 2010 is not functioning properly. Search therefore in the search engine of their choice to "uninstall Office 2010".
