How to Reinstall Samsung Settings App on Galaxy Book4 Edge

If you recently clean-installed Windows, replaced your SSD, or accidentally uninstalled your factory applications on the Samsung Galaxy Book4 Edge, you have likely discovered that getting the Samsung Settings app back isn’t as simple as clicking “Install” in the Microsoft Store.

Many users find that after reinstalling the app, it flashes on the screen for a split second and instantly crashes. This happens because the Microsoft Store frequently gets confused by the new ARM64 Snapdragon X Elite architecture and mistakenly serves a legacy version (3.6.3.0) designed for older, low-power ARM laptops. This older binary is fundamentally incompatible with your modern Copilot+ PC, causing a hard crash in SharedLibrary.dll.

To successfully reinstall the app, you must completely purge the broken legacy templates cached by Windows and force-install the genuine, modern unified Samsung application layer. Here is the definitive guide to doing it correctly.

Step 1: Open PowerShell as an Administrator

Because factory application frameworks are deep system-level components, standard uninstallers leave corrupted setup files behind. We need to use elevated terminal permissions to clear them out.

1. Right-click the Windows Start Menu button.
2. Select Terminal (Admin) or PowerShell (Admin).

Step 2: Purge the Legacy Application Identity & Unblock Files

Before installing the correct version, we must unlock the underlying framework files (which are often held hostage by silent background processes like Samsung Welcome or Dolby Access) and wipe out the legacy cached package.

Copy the entire block of code below, paste it into your Administrator PowerShell window, and press Enter:

PowerShell

# 1. Forcefully close background processes holding locks on the system files
taskkill /f /im DolbyAccess.exe /im SamsungWelcome.exe /im GalaxySetting.exe /t

# 2. Delete the local, corrupted application state cache directory
Remove-Item -Path "$env:LOCALAPPDATA\Packages\SAMSUNGELECTRONICSCoLtd.GalaxyBook_wyx1vj98g3asy" -Recurse -Force -ErrorAction SilentlyContinue

# 3. Eradicate the legacy version from all User Accounts AND the Windows system staging image
Get-AppxPackage -AllUsers *GalaxyBook* | Remove-AppxPackage -AllUsers -ErrorAction SilentlyContinue
Get-AppxProvisionedPackage -Online | Where-Object {$_.PackageName -like "*GalaxyBook*"} | Remove-AppxProvisionedPackage -Online -ErrorAction SilentlyContinue

# 4. Repair and re-index the foundational ARM64 .NET framework with a forced override
Get-AppXPackage -AllUsers -Name "Microsoft.NET.Native.Framework.2.2" | Where-Object {$_.Architecture -eq "Arm64"} | Foreach {Add-AppxPackage -DisableDevelopmentMode -ForceApplicationShutdown -Register "$($_.InstallLocation)\AppXManifest.xml" -Verbose}

Look for the green VERBOSE: Operation completed message at the bottom of the console, which confirms the system has been successfully cleared.

Step 3: Flush the Microsoft Store Component Cache

To stop the operating system from trying to redownload the old, broken installer files from its local memory cache, trigger a quick store reset:

1. Press the Windows Key + R to open the Run dialog box.
2. Type wsreset.exe and click OK.
3. A blank, black command prompt window will open on your desktop. Leave it alone; it will automatically close itself within 15 seconds and pull up a fresh window of the Microsoft Store.
4. Once the Microsoft Store window appears, close it.

Step 4: Reinstall the Modern App via WinGet (Using Product IDs)

To bypass the glitchy Microsoft Store graphical interface completely, use the Windows Package Manager (winget) to pull the specific, modern software branch intended directly for Copilot+ Snapdragon X systems.

Go back to your Administrator PowerShell window, run these two commands in order, and press Y if prompted to agree to repository terms:

PowerShell

# Reinstall the modern native Samsung Settings package via its explicit Product ID
winget install 9P2TBWSHK6HJ --source msstore

# Install the required companion Runtime framework
winget install 9NL68DVFP841 --source msstore

Verification

Once the command terminal reports that the packages are successfully installed, close PowerShell. Click your Windows Start menu and launch Samsung Settings.

The app will now open immediately, remain perfectly stable, and give you full control over your keyboard backlighting, battery care profiles, and outdoor display modes.

To double-check your work, go to Settings > Apps > Installed Apps > Samsung Settings > Advanced Options. Under the specifications, you will see that the app version is no longer stuck on the broken 3.x branch, but is running a native 7.x.x.x version build optimized specifically for your Galaxy Book4 Edge.
