Uninstalling Keenious can be done from within Microsoft Word itself, though it will vary based on what version of MS Word you have.
There are two options:
Option 1
Simply right-click the Keenious logo on your home ribbon.
Select remove add-in.
Option 2
Navigate to Add-ins on the home ribbon, or via File and then Options.
Click on My Add-ins.
Click on the three dots beside 'Keenious' and select Remove.
