Why would you use libre office when you can get Office 2016 Pro for £4 of Fleabay? I have got all my grandkids and myself cheap Office from Fleabay and never had a problem. I have had mine a few years now but I only use Word, the kids use the full suite. Just go on Fleabay and search Microsoft Office, as I said, I immediately found 2016 pro for £4, there may be some cheaper!
