Hi,
Welcome to Microsoft Community.
I would like to know if you have previous version of Office installed in the computer.
If yes let us uninstall it, to do that press windows + r (on the keyboard) at the same time and try in appwiz.cpl. From the list of programs installed choose previous version of Office and uninstall, after which let us try repairing Office 2016 and check.
You may also try changing the default program and check.

I hope the above suggestion helps. If you need further assistance, get back to us and we will be glad to assist you.
Thank you.
