Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi @Mohd Marezuan Ahmad Marzuki
Good day! Welcome to Q&A forum!
Thank you for reaching out. I understand how confusing it can be when the Microsoft 365 installation appears stuck and then completes hours later. This behavior usually happens because the Click-to-Run installer continues working silently in the background, but certain factors can delay the process.
Here are some steps to help resolve the issue and ensure a smooth installation in case you experience the same issue while installing Microsoft 365:
- If the installer disappears, please avoid from retrying the installation. Instead, restart your device and navigate to Settings > Apps > Installed apps (Windows 11) or Control Panel > Programs and Features (Windows 10) > Look for "Microsoft 365" or "Microsoft Office." to check. If it's not there, kindly wait for 15 to 30 minutes and check again.
- Remove remnants of previous installations Use Microsoft’s official Uninstall Microsoft 365 from a PC - Microsoft Support to completely remove any leftover Office components before reinstalling.
- Disable interfering software Temporarily turn off VPN, third-party antivirus, and encryption tools, then restart your PC and try the installation again.
For reference: Office is taking long to install - Microsoft Support
- Run the installer as Administrator and check your network Ensure you have a stable internet connection and right-click the installer to select Run as administrator.
- Use the Offline Installer If the online installer continues to stall, download the full offline installer from your Microsoft account page.
For reference: Use the Office offline installer - Microsoft Support
- Monitor background installation If the installer window disappears, open Task Manager → Processes and look for OfficeClickToRun.exe. If it’s running, the installation is still in progress.
These steps typically resolve the issue. If the problem persists, please let me know so I can provide you with further supporting steps.
