installing office 2019 on Mac OS high Sierra 10.13.6
I bought a second hand Mac(2011)just for research purposes and was looking to install office 2019 in it. I managed to purchase a one time subscription with license key however it does not allow me to continue and prompting a newer version of 10.14 or higher. Can somebody tell me if this is still possible or not? I know that Microsoft already ended support for this model but I should be able to install it. It does not allow me to update my Mac either.
thanks
