Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Try this in order on the Windows PC:
- Restart the PC first A Microsoft 365 install can sometimes finish in the background or get unstuck after a restart.
- Check whether Microsoft 365 actually installed After restarting, look for Word or other Office apps from the Start menu. In some cases, the install completed even though it looked stuck.
- If the installer is still taking too long, install again using a wired connection A wired connection can speed up installation compared to Wi‑Fi.
- Use the offline installer if the normal installer keeps hanging The offline installer can help bypass proxy, firewall, antivirus, or internet connection issues during installation.
- Temporarily turn off third-party antivirus software Antivirus software can interfere with installation. Re-enable it after Office finishes installing.
- Repair Microsoft 365 / Office

- Choose Online Repair > Repair
- Right-click Start > Installed apps
