Uninstalling Catalina 10.15.4
I have an old ( 2103 Macboook ) I recently installed Catalina 10.15.4 Now my original Word app won't work so I can't retrieve my work. Microsoft says I have to upgrade to 365 ( which I can't afford as a pensioner ) Can I uninstall Catalina and reinstall an old version that will give me access to my original Word program.Help please.
