You must pay attention to the instructions and follow them to the letter. Uninstall all Office products and OneDrive. Reboot your computer. Read the instructions carefully before installation. I had to use the "Activate Office by phone" method for both my installations and it worked flawlessly. I chose to have the activation service send its response via text to my phone. It sends you a link that takes you to the web page with the codes you need. I did not have to ask for help from the support area; the instructions are clear. Be sure to read your email carefully and follow the instructions. I am very happy with my purchases.
