Thank you for the update.
When you say it did nothing what exactly happened? After removal some icons remain in the start list/menu & these need to be manually removed from the Start menu but the program is removed.
Apps are under their own tab on the left side, once you double click on the app a command prompt will open to uninstall the app, then Revo should show the option to scan for leftovers, once chosen & completed it will show a list of files (if any remain) for you to manually select then choose delete. It will then either move to a remaining folders screen for the user to delete or a completed screen if no further leftovers remain.
Those may be apps which were pre-installed with the pc or just links to the office website. Revo will only show installed apps & programs.
You can try manually removing the entries.
