copilot will not install

Question

Copilot speaker was not working on computer, so I followed trouble-shooting instructions provided on my cell phone copilot. Eventually I was told to remove the app and reinstall, and it will not allow me to reinstall. I am now forced to use 365, which is continually restarting on me ... maybe time to try something else. Here are my computer details: Device name DLB

Installed RAM 32.0 GB (31.8 GB usable)

Hello Darren Brumfield,

Since the Store path already isn't letting you reinstall Copilot, the next things to try are a level below that. These are in order of how invasive they are.

1. Re-register the existing Copilot package via PowerShell.

Often when "Store won't reinstall" happens, the package is still on disk but its registration is broken, so Store thinks it's already installed and refuses to do anything. Re-registering fixes that without touching files. Run this in PowerShell (administrator):

Get-AppxPackage -AllUsers *Microsoft.Copilot* | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppxManifest.xml"}

Then restart the PC and check Start for Copilot.

2. If that returns nothing, install Copilot as a web app through Edge.

This is the cleanest workaround when the Store path stays broken — it gives you a real Copilot window pinned to Start/taskbar, independent of the Store package:

• Open Microsoft Edge and go to https://copilot.microsoft.com.
• Click the ... menu (top right) > Apps > Install this site as an app.
• Give it a name and click Install. It will pin to Start and you can drag it to the taskbar.

3. If Store reinstall is failing across other apps too, repair the component store.

Open Powershell (Admin) again and run, one after the other:

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

Restart, then retry the Store install from https://apps.microsoft.com/detail/xp9cxngppj97xx.

4. Quick check while you're at it.

Confirm Windows is signed in with a Microsoft account (not a local account) under Settings > Accounts > Your info, and that the Store region under Settings > Time & language > Language & region matches a supported one. Either of those being off can make the Store quietly refuse Copilot.

On the side note about Microsoft 365 restarting on you — that's unrelated to Copilot. Easiest first step is Settings > Apps > Installed apps > Microsoft 365 > Modify > Quick Repair, and if that doesn't hold, run it again and pick Online Repair. Worth opening a separate thread for it if Online Repair doesn't fix it, since the diagnostics are different.

Copilot on Windows is installed and removed like any other app. If it was uninstalled and now won’t reinstall, use these steps to get it back and verify it’s working.

1. Confirm Copilot is actually uninstalled
   • Open Settings > Apps > Installed apps.
   • Search for Copilot.
   • If it appears, select the … menu and choose Uninstall to fully remove it.
   • Restart the PC after uninstall completes.
2. Reinstall Copilot from Microsoft Store
   • Open Microsoft Store from Start.
   • Search for Copilot or go directly to the Copilot app page using this Store entry: Microsoft Copilot app.
   • Select Get / Install.
   • After installation, Copilot should appear in Start and can be pinned to the taskbar.
   If the Store install fails, check that Windows is online and signed in with a Microsoft account, then retry.
3. If reinstall still fails, use the PowerShell method (advanced/IT-managed scenarios)
   • IT administrators can remove or prevent the Copilot app using PowerShell and AppLocker. If this was configured on the device (for example by an organization image or policy), Copilot installation may be blocked.
   • In that case, an admin should review any AppLocker or TurnOffWindowsCopilot-related policies and remove or adjust them so the MICROSOFT.COPILOT package is allowed, then retry installation from Microsoft Store.
4. If the issue is specifically with Copilot in Microsoft 365 apps (Word, Excel, etc.)
   • If the Copilot button is missing or disabled in Microsoft 365 Apps, follow the steps in How to find and enable missing Copilot button in Microsoft 365 apps (linked from the Copilot troubleshooting article).
   • If Copilot still doesn’t appear or work in Microsoft 365 Apps, an admin must verify:
     • A valid Microsoft 365 Copilot license is assigned to the user.
     • Copilot is not blocked by organization policies or privacy settings.
   • For license or connectivity issues with Copilot in Microsoft 365, run the Copilot license troubleshooter or Copilot connectivity troubleshooter from the Get Help app.
5. If none of the above works
   • Run the Copilot troubleshooters in Get Help as described above.
   • If the Copilot app still cannot be installed or used, the remaining option is typically a repair or reinstall of Windows (for example, a reset while keeping personal files) to restore a clean app and Store environment.
