I was informed by the store that sold me my Mac that I could install office 64 bit and remove office 32 bit, but when I logged on to Microsoft I cannot findan option to do this. Please advise how I can be sure, if I need to purchase a newer version.Many Thanks. Hi Jim,I am quite confused about my sudden current position:Mac insistently reminded me that I should upgrade to Catalina, and when I finally agreed (half knowing what I did) amidst a number of other distracting things and the upgrade was finalised in the end I was just missing my 2011 MS Office for Mac. Please advise how I can do this.Also the new versions of office do not specify if they run using 64 bit or 32 bit. ![]()

Dec 23, 2015 Mac OS X Speciality level out of ten: 0. Microsoft issued another update, so I have now installed the Office 2016 updates and they were successful so far. But still missing a bunch of features from Office 2011. Beats me how Apple let them get away with doing that.

Microsoft will be moving to a new codename format starting in 2019 [..] now known internally as 19H1. [..] The '19' stands for the year in which the update is released, and the 'H1' stands for the first update of that year. [..] following that format, the update coming after 19H1 would be codenamed 19H2, being the second update for 2019, followed by 20H1, 20H2, and so on.
