Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello Kipp,
Welcome to Microsoft Community.
To resolve this issue let us know the following:
Are you installing a 64 Bit version of Office 2016 or a 32 Bit version of Office 2016? In case you are trying to install a 32 Bit version of Office then this error might appear if there is a 64-Bit version of Microsoft Office installed or there are some components of Microsoft Office. This error could also appear if you had a 64-Bit version of Office installed earlier (which has now been un-installed) but there are still some remnants of the 64 Bit version of Office currently.
Since you have already removed/un-installed a previous installation of Office, to resolve the issue make sure to run the FIXIT (Office removal tool) to un-install any remnants of Office from your computer.
Run the FIXIT in the following Microsoft Article:
Once un-installed make sure to restart the computer and then re-install Office 2016 from the My Account page (URL: http://office.com/myaccount).
