Are all on Microsoft. Be sure to have your purchase information ready when you call this in.
I sure hope this isn't one of those bogus reseller issues. Those get everyone upset.
PS. Wrong word corrected.
We bought Office 365 Home that is good for 6 people. We have installed it once. Now one of the users is trying to install and gets an error "This product key has already been used. Please sign in with the active Office account that you used with this product key before or enter a new product key here."
What do we need to do to get this installed on other devices? Thanks!
