It is my understanding of the standard academic license for Microsoft
products do not permit upgrades. I presume this enforced in software. I
don't have it to check for you. Best you read the EULA for other
restrictions that may get in you way.
I gotta mention, though, that even though on your home computer, you are
still when you install the software agreeing to licensing terms.
Hope this is useful to you. Let us know.
