Solutions to failed Microsoft Edge installation include: 1. Check whether the system version is compatible. You need to view and upgrade the system through winver; 2. Use Microsoft's official offline installation package to obtain the .msi or .exe files of the corresponding system from the enterprise download page and run as an administrator; 3. Clean the remaining files of the old version, end the Edge process, delete the relevant installation directories and user data folders, and execute Get-AppxPackage -allusers Microsoft.MicrosoftEdge | Remove-AppxPackage after restarting; 4. Close the security software and agents, temporarily disable the antivirus software or firewall, check the proxy settings and try to change the network environment; 5. Run the system file check tool, run the command prompt to execute sfc Restart after /scannow and DISM /Online /Cleanup-Image /RestoreHealth; 6. Check group policy restrictions in the enterprise environment, and check whether the "Block Microsoft Edge installation" policy is enabled and disabled through gpedit.msc. If it still fails, you can try to update the system through Windows Update, replace the device to download the installation package, or view the edge_*.log log file in the %temp% directory for troubleshooting. The above steps can basically solve the installation problem.

Microsoft Edge installation failure is a common problem and may occur after Windows system updates, manual installations, or system reinstallation. Although Edge is the default browser for Windows, the installation or update process may fail in some cases (such as system file corruption, permission issues, or network restrictions). The following are several practical solutions to help you troubleshoot and fix Microsoft Edge installation failures.

1. Check whether the system version is compatible

Microsoft Edge has multiple versions (such as Stable, Beta, Dev), and has requirements for Windows system versions:

• Windows 10 version 1803 or later
• All versions of Windows 11
• Windows 7/8/8.1 is not supported (unless you use legacy Edge or manually install special versions)

? suggestion:

• Press Win R , enter winver to view the system version.
• If the system is too old, please upgrade to a supported version of Windows first.

2. Use Microsoft's official offline installation package

If you fail to download and install from the Microsoft official website, it is recommended to use an offline installation package (Offline Installer) to avoid failure due to network interruption or CDN problems.

? Operation steps:

1. Visit the Microsoft Edge official corporate download page:
   http://ipnx.cn/link/0643aba5bbf86ece22ee145f322a9c6a
2. Choose a version (64-bit/32-bit) and language (such as Simplified Chinese)
3. Download .msi or .exe offline installation package
4. Run the installer as an administrator

? Tip: .msi files are more suitable for enterprise deployment, .exe is more suitable for ordinary users.

3. Clean up the remaining files of the old version

Installation fails sometimes because the old version is not fully uninstalled, or the registry/cache file conflict.

? Solution:

1. Open Task Manager and end all Microsoft Edge processes
2. Delete the following folder (if it exists):

    C:\Program Files (x86)\Microsoft\Edge\
   C:\Program Files\Microsoft\Edge\
   C:\Users\<your username>\AppData\Local\Microsoft\Edge\

3. Clean the app packages with PowerShell (for Windows 10/11):

    Get-AppxPackage -allusers Microsoft.MicrosoftEdge | Remove-AppxPackage

4. Restart the computer and try to install it

4. Turn off security software and agents

Some antivirus software (such as 360, McAfee) or corporate network agents intercept Edge installation.

? Suggestions:

• Temporarily shut down the firewall or antivirus software
• Check if a proxy is used (Settings → Network and Internet → Proxy)
• Try to switch the network (such as using a mobile phone hotspot instead)

5. Run the system file check tool

System files corruption may cause installation failure.

?? Use the command prompt to fix:

1. Open a command prompt as administrator
2. Run the following commands in turn:

    sfc /scannow
   DISM /Online /Cleanup-Image /RestoreHealth

3. Restart the computer after completion

This can repair system images and component storage and improve installation success rate.

6. Check restrictions through group policy or registry (enterprise environment)

If you operate on a company computer, you may be prohibited from installing software by Group Policy.

? Inspection method:

• Press Win R and enter gpedit.msc (The home version may not have this function)
• Navigate to:
  計算機配置→ 管理模板→ Windows 組件→ Microsoft Edge
• Check whether the "block installation" policy is enabled, and if so, disable it

Basically these common causes and solutions. If you have tried all the above steps and still failed, you can try:

• Update the system using Windows Update (Edge is sometimes automatically installed through system updates)
• Download the installation package on another device to avoid corruption of source files
• View the installation log (usually in the %temp% folder, look for edge_*.log )

Not complicated, but it is easy to ignore details. Patiently investigate step by step, basically all can be solved.
