If you’re having trouble with activating your Office key then please make sure you are using redeem.microsoft.com and not setup.office.com
If you’re still having trouble then feel free to contact our customer support.
Sometimes when you have an error with your Windows key it doesn’t necessarily mean that the key is faulty. If your key has an error saying it’s used then try the method in the video below.
Otherwise, If you have an error saying your product is invalid then check your version to make sure it’s the same as the key. For example, ‘Home’ will not work on ‘Home N’ or ‘Pro’. If you purchased the incorrect key and need it exchanged then feel free to contact our customer support.
