Docs girl, this is very simple to fix in the short term. Go online and find LibreOffice. Only get it from their site, nowhere else please. Install that program. It is a Microsoft Office replacement, and a very good one. It is what I had to use when my mom had to get a new computer and all her docs were in a very old Microsoft Works format. Despite her having a brand new Office package on her new computer, the new Office could not open its own older doc versions. Although I am highly computer literate and a Microsoft user and general supporter, I do not have time for nonsense, so I promptly installed LibreOffice on my laptop to up-convert and open her vital tax spreadsheets. It was done in seconds with no loss of data. And, I am now going to keep LibreOffice for myself, because it looks and performs almost exactly like Office......for free! Woot!
