How to Fix Microsoft 365 Copilot Office Hub Error “Windows Cannot Find C:\ProgramFile”

If you see the error “Windows cannot find ‘C:\Program Files\WindowsApps\Microsoft.MicrosoftOfficeHub_... \M365Copilot.exe’”, it typically means the Microsoft Office Hub package (the launcher for Microsoft 365 and Copilot) is corrupted or missing. Follow the steps below to restore Office Hub, Copilot shortcuts, and fix related errors.

What is Microsoft.MicrosoftOfficeHub?

Microsoft.MicrosoftOfficeHub is the central launcher that connects Office apps (Word, Excel, PowerPoint, Outlook) and the Microsoft 365 Copilot interface. When this package is damaged, shortcuts or Copilot links (like M365Copilot.exe) may fail to open.

Step 1 — Repair Microsoft 365 / Office via Control Panel (Recommended)

This is the official, most reliable method:

1. Press Windows + R, type control, and press Enter to open Control Panel.
2. Go to Programs > Programs and Features.
3. Select Microsoft 365 (or Microsoft Office) and click Change.
4. Choose Quick Repair first — try the app. If the issue persists, repeat and select Online Repair.
5. Quick Repair fixes common problems offline; Online Repair reinstalls Office components from Microsoft servers.

Step 2 — Repair from Settings (Alternative)

If Programs and Features does not list the package in your environment, use Settings:

1. Open Settings > Apps > Installed apps.
2. Find Microsoft Office Hub (or Microsoft 365 (Office)), click the ⋮ menu.
3. Choose Advanced options > Repair. If not resolved, choose Reset.

Step 3 — Reinstall Office Hub from Microsoft Store

If repair doesn't work, reinstall the package:

1. Open the Microsoft Store.
2. Search for "Microsoft 365" or "Office" and install the app again.

Step 4 — Re-register Office Hub (PowerShell)

If Office Hub still fails after reinstalling, re-register the package using PowerShell (Admin). This often fixes registration/manifest issues.

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

Step 5 — Run System File Checker (SFC)

When multiple components or apps behave incorrectly, repair Windows system files:

sfc /scannow

Step 6 — Clear WindowsApps Cache (Optional)

If other steps fail, remove the local package folder and reinstall from the Store:

1. Press Windows + R, paste: %localappdata%\Packages\ and press Enter.
2. Find folder names like Microsoft.MicrosoftOfficeHub_8wekyb3d8bbwe.
3. Rename (add _old) or delete the folder, then reinstall Office Hub from the Microsoft Store.

Quick summary

1. Control Panel → Programs > Programs and Features → Change → Quick Repair (then Online Repair if needed).
2. Settings → Apps → Repair / Reset the Office Hub.
3. Reinstall from Microsoft Store.
4. Re-register with PowerShell (Admin).
