my word office is not starting ,it's showing microsoft office can not verify the license for this product .

Use this order to fix the license verification error in Word:

1. Sign in with the correct account
   • Open Office and sign in with the account used to buy or activate Office.
   • If more than one Microsoft account exists, try all personal accounts, and if this is a work or school copy, use the work or school account.
   • Check whether the Office product or Microsoft 365 subscription appears under Services & subscriptions: https://account.microsoft.com/services
2. Check for multiple Office installations
   • Open Control Panel > Programs > Programs and Features.
   • Search for Office.
   • If more than one version is installed, uninstall the version not being used.
   • Restart the PC.
3. Run Office as administrator
   • Close all Office apps.
   • Select Start, type Word.
   • Right-click Word and select Run as administrator.
   • Select Yes if prompted.
4. Check date, time, and time zone
   • Close all Office apps.
   • Select the date/time in the lower-right corner.
   • Open Date and time settings.
   • Turn on Set time automatically and, if available, Set time zone automatically.
   • Reopen Word.
5. Update Office
   • Install the latest Office updates, because updates can include activation fixes.
6. Check connectivity settings
   • Temporarily check whether firewall, antivirus, or proxy settings are blocking activation.
   • For proxy in Windows: Start > Settings > Network & internet > Proxy.
   • If a manual proxy is enabled and not required, turn it off and save the change.
   • If antivirus or firewall is disabled for testing, turn it back on afterward.
7. Repair or reinstall Office if the error continues
   • If Office is stuck during update/repair/uninstall, restart the PC first.
   • If needed, use the Microsoft uninstall troubleshooter to completely remove Office, then reinstall it.
   • Important: the uninstall troubleshooter does not uninstall Office 2024, and it requires Windows 10 or higher.
8. If Office was preinstalled on a new PC and keeps returning to setup
   • Exit all Office apps.
   • Go to Services & subscriptions.
   • Find the Office product and select Install to reinstall from the account that owns the license.
