Click on My Add-ins under the Insert menu. All Microsoft Office (Word, Excel, Power Point) applications have the same menu design at the top page.
You'll then get an overview of the add-ons that currently are installed on your Office package.
Scroll until you find the Scrive eSign application and then click the three dots at the corner.
You will then see a window where you get three choices, click on "Remove".
