I purchased 0ffice 365 a while back and used it for several years. I then let it expire because I thought I could replace it with Libre Office. it's been quite a while now since it expired and my wife has complained that things aren't working well on her computer with Libre. As a matter of fact, I don't much care for it either and I don't do 1/10 of the stuff the wife does.
My question is, I purchased a card with McAfee and 365 on it (Family version) and wondered if there would be a problem to uninstall the old version before installing the one recently purchased or is it not necessary?. My OS is Windows 10 version 21H1.
