Office upgrade problem

Microsoft does not offer a free update from Office 2011 to 2016 or later.

If you have Office for Mac 2011 or earlier, you can either subscribe to Office 365 or you can make a one-time purchase. See: https://products.office.com/en-us/buy/compare-microsoft-office-products-for-mac?ms.officeurl=mac-compare-redir

Or the free Microsoft Office on the web: https://products.office.com/en-us/free-office-online-for-the-web

Or Google Docs: https://www.google.com/docs/about/

Other options include using the free and very good Libre Office https://www.libreoffice.org/

or Apple's Pages and Numbers

32 bit apps do not work with Catalina. You can buy 64 bit Office from Microsoft. Office 2016 (updated), Office 2019, and Office 365 are all 64 bit and work with Catalina.
