I have a (July 2017) Microsoft Surface Book with Office 2010 Pro installed. Everything was working fine for several months until my Office 2010 suite somehow decided recently that it was not activated any more. I have tried to re-activate it on-line but that failed and telephone activation is no longer available. This leaves me with some questions.

1.. Is there any way to get rid of the RED bar that is now showing on the title bar of every Office app that I open?

2.. Using my Valid KEY, I downloaded the software file for re-installing Office 2010. If question 1 cannot be resolved, should I uninstall the existing Office before installing again using the downloaded file? Will doing this screw up my Outlook settings and contacts…I have backup copies of my archive and outlook pst files.

2.. Can I install from the downloaded file without uninstalling the original Office first.
