If the issue occurs when attempting to install Edge on Windows 10/11, try the recommended solutions below. However, before initiating the process, we advise backing up your system registry or at least, create a restore point for the computer.

  3. Locate the registry key shown below;
  4. Once you’ve reached the location, insert the entry shown below on the left panel before clicking Delete:
  5. Exit the Registry Editor and reboot your system for the edits to take effect.

Once your system has completely rebooted, download MS Edge, or if already downloaded, right-click on the installation file and click Run as administrator. When the UAC prompt appears, click Yes. Edge will then install without encountering an issue.

More Information

For those wondering why these two platforms are experiencing the same error code, let us briefly help you with that. Recently, Microsoft Edge browser crossed over to Chromium platform, which means it now uses the same engine as Google Chrome. This is quite visible in the way Edge currently looks and functions. However, it managed to keep most of its features such as Cortana search, Audio cast, wireless connection to cast videos and images, and InPrivate Mode. Since both browsers are Chromium-based, it makes sense for the same error code to appear on both platforms.
