Tell customers to go to office.com\setup when they buy a new product.
Office Home & Student Instructions on the card purchased at a retail store says to go to office.com/myaccount. Nowhere does it explain how to change the past version of Office Home & Student displayed. There was no why I could load the new office 2016 version just purchased. It only listed Office Home & Student 2013, my previous purchased software.
Also, I did not want Office 365 because I travel to remote Alaska where there is no internet connectivity. I did not buy Office 365 I bought what I think is Office Home & Student FULL version. I hope that's correct.
