If you have issues uninstalling Vivaldi while using Windows 10, Windows 10 provides two different UIs to add/remove programs: the old style UI, and a new modern look (see screenshots below).
Only the older style UI will allow a non-admin user to uninstall a single user installed program.

Older add/remove program Windows UI

New add/remove programs UI in Windows 10.

 

So to uninstall Vivaldi from Windows 10, make sure that you are using the old add/remove UI.
To ensure that you are, follow these steps:

  1. Use ⊞ WinKey+R to open the “Run dialog”
  2. Type: control appwiz.cpl
  3. Press “OK”
  4. Scroll down to the “Vivaldi” entry and double click it

Alternatively, you can also uninstall by using the setup.exe we include with Vivaldi and calling it directly, e.g. assuming version number 1.7.735.29, start the run dialog and then issue the following:

%LOCALAPPDATA%\Vivaldi\Application\1.7.735.29\Installer\setup.exe --uninstall --vivaldi

If you still run into issues when attempting to uninstall Vivaldi from Windows 10, please get in touch with our support team on vivaldi.com/contact.
