And like other browsers, it includes the reading view, the bookmark import, the display of the bookmark bar and the InPrivate navigation.

How to Fix Error 0xa0430721 when Installing Edge on Windows 10

If you try to run the Microsoft Edge installer directly from another browser after downloading it, you may receive this error message. This error mainly occurs because Edge is installed directly from other browsers. Most users download Edge from other browsers like Chrome, Firefox, etc. After downloading, many users click Run directly to install the installation file directly. At this point, you receive this error 0xa0430721 after the UAC prompt.

If error 0xa0430721 occurs when installing Edge on Windows 10, you can try the recommended solution below to fix the problem.

We highly recommend that you use this tool for your error. Furthermore, this tool detects and removes common computer errors, protects you from loss of files, malware, and hardware failures, and optimizes your device for maximum performance. This software will help you fix your PC problems and prevent others from happening again:

  • Step 1 : Install PC Repair & Optimizer Tool (Windows 10, 8, 7, XP, Vista).
  • Step 2 : Click Start Scan to find out what issues are causing PC problems.
  • Step 3 : Click on Repair All to correct all issues.


Since this is a registration process, it is recommended that you back up the Registry or create a system restore point to take the necessary precautions. Once you’re done, you can do the following:

  • Open the Downloads folder with the installer and run it.
  • You can also try removing the HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\EdgeUpdate\Clients{F3C4FE00-EFD5-403B-9569-398A20F1BA4A} key from the registry editor (regedit).

The next step is to download and reinstall Microsoft Edge. A system restart should normally not be necessary after deleting the above registry key. However, I recommend running one to ensure that the registry is restored and all changes are applied.

Once this is done, Microsoft Edge should install and work properly regardless of the browser used to download the installer.

Execute the Commands SFC Scan and DISM in Powershell

Right-click Start, select PowerShell with the administrator, and type the following:

  • DISM /Online /Cleanup-Image /StartComponentCleanup
  • DISM /Online /Cleanup-Image /RestoreHealth


Keep in mind, however, that Microsoft Edge is still under development and the problems with the installer or with the use of the browser are not necessarily very surprising. With these preview versions, you can test the app before launch, send feedback to Microsoft, and troubleshoot the stable version.
