I installed a new purchase of Office Home 2024 and activated the product key on a new laptop computer. In the same evening, I found a hardware issue (USB connector failure). I uninstalled Office Home 2024 before returning the computer to the seller and receiving a new one from them. I downloaded Office Home 2024 on the replacement laptop and when I try to activate it, I get an error that it has already been installed on another computer. How can I active Office Home 2024 on my computer?
