I had installed Office Home & Student 2016 on my PC several years ago using a key. This PC took a coffee spill and stopped working. I have no way of accessing this PC to uninstall Office 2016. I have now bought a new PC which came installed with Office 365. It keeps asking me to start a subscription, which I'm not interested in. I'd like to install a non-subscription Office 2016 on the new PC and activate it with my current key. How should I proceed?
