... check your MS account online, it will show if you have the license permission to install O365 on multiple machines. yours may be different than mine, but i have a license through my school system that lets me install O365 on up to 5 machines at the same time. when i log in to my MS account, it shows what machines i have installed on and how many licenses i have available. i can "delete" a computer if i don't need office on it any more or if i stop using it and have a new computer for installation.
also the MS Office "apps" are FREE on the Go2, and i actually prefer those as they are leaner and meaner, and do really anything i need except for the occasional super-duper powerpoint or something that requires fhe full office installation to create. that really doesn't come up very often and is a "power user" thing that is hardly ever needed.
hope this helps
