Steps:
- Press Windows + R, type
services.msc, and press Enter - Scroll to Microsoft Office Click-to-Run
- Right-click → Restart

Steps:
- Download the Microsoft Office Uninstall Tool
- Select Remove All Office Versions
- Restart your PC
- Try reinstalling Microsoft 365
This fixes 70–80% of cases.
✔ Fix 3: Run System File Checker (SFC) + DISM

Temporarily disable:
- Windows Defender Real-Time Protection
- Third-party antivirus (Norton, McAfee, Bitdefender, etc.)
- Any active VPN
- Firewall blocking rules
Re-enable everything after installation.
✔ Fix 5: Use the Office Offline Installer

- Download the full setup file (~2–3 GB)
This bypasses most network-related failures.
✔ Fix 6: Reset Office Installation Components

icacls "%programfiles%\Microsoft Office" /reset /T /C - Restart your PC
