I installed Excel and Word on Monday. Each is app is available as a separate download not like the desktop version where you can install the whole Office package at once. Word was working fine Monday but last night wasn't working and it referred me back to the store where all it said was I owned it. Excel is still working fine. Each app is touch friendly abut i don't have touch. One big difference between Office 2013 is the Windows 10 versions are missing the ribbons.
