MS Office installation

what is easier to perform? Installing office using Your Microsoft account Subscription or Installing office using Installer from local storage device?

1. Robert needs to use Excel to figure out how much money his business makes. Robert doesn't have the money to subscribe to Microsoft Office, but his teacher gave him an old copy of MS Office 2013.

2. Joseph needed to construct a project poster to show his creativity that looks like a movie poster using MS Word; luckily, he got some office 2019 from a DVD disc.

3. Ding has to install Power Point so that he may give a presentation to his class about several volcanoes. He doesn't have an offline installer on hand, but he does recall that his Microsoft Office account has a subscription.
