Hello Kris,

Welcome to Microsoft Community.

I am sorry that you are facing issues with upgrading to Office 2016 from Office 365 on your computer.

First, we need to make sure to remove all remnants of previous installations of Office from the computer. To remove the remnants of Office 2013 and partially installed Office 2016 you may install and run the following Office FIXIT tool: http://support.microsoft.com/kb/2739501

Once completed make sure to restart the computer. Check if you are now able to re-install Office 2016. If not, and if you get the same error message again then let’s try the following steps.

Check what type of internet connection do you use (Wired, Wireless or Wi-Fi etc.)?

If you are using a wireless/Wi-Fi connection then you may try to hardwire the connection. Once this is done we will try to remove all the remnants of all previous installations/installation attempts of Office from the computer:
