Fix: Can’t Set Opera as the Default Browser
Check if you have the necessary permissions to set Opera as default
- Some of our readers can't set Opera as the default browser when there’s a corrupted or incomplete installation.
- The reason behind this problem might be the fact that you already have another version of the browser installed.
- Make sure you have the right permissions to change the default settings and that you install the app for all users.

Opera is undoubtedly one of the most feature-rich and customizable browsers. Therefore, many of its users no doubt prefer to set Opera as the default browser in Windows 10. However, many readers reported that they can’t set Opera as the default browser.
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.
Now that we know what potential issues are hindering this operation, let’s see how we can fix this problem.
How do I change my default browser from Internet Explorer (or Edge) to Opera?
