If you downloaded the genuine Mac Office 2016 just like me, but you didn't include an activation tool in it.
Or if you used the time machine to restore the application and lost the activation information, then this tool is right for you.
I have provided the activation tool for this software separately, so you do not need to download the complete installation package + activation tool again.
This tool is collected on the internet. If infringe your rights, please contact me. I will delete it.
