Click on "Get Add-ins" under the "Insert" menu.
You can then search for the applications that you want to install, type in "Scrive" and then select "Add".
After installation a new menu has appeared named "Scrive eSign".
After clicking on the "Scrive eSign" menu you click on the "Scrive eSign" button to setup the service.
Click on the blue log in button to setup the Scrive add-in.
To login you first need to login, if you don't have an account, you can click the "Get started with Scrive eSign for free" link in blue.

Now the application is installed and you're ready to send your first document for signing!
