Why can’t I make Opera my default browser?

You can still utilize Opera without it being your default browser. However, your default browser will always open whenever you click webpage hyperlinks in documents and software.

So, let’s go through a couple of reasons why you can’t set Opera as the default browser:

  • Another version is already installed If you have installed the developer or the portable version of Opera, you will not be able to fully install a stable version of Opera, hence, you won’t see it in the Default app section.
  • It is not installed for all users – During the installation of Opera, make sure you check the option to do so for all the users on the PC. Otherwise, check if you can set it up as default on the main account.
  • You don’t have permissions – If you’re not the administrator, you might not change the default browser. This guide on how to get administrator rights on Windows 10 will help you.
