Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
If Excel or Word shows "Microsoft Office can't find your license for this application", use this order:
- Sign in with the correct Microsoft account
- Open an Office app.
- If prompted, sign in with the account used to buy Office or Microsoft 365.
- Using the wrong account can cause "We couldn't find any Office products".
- Check for multiple Office installations
- Having more than one copy of Office installed can cause activation conflicts.
- If there are multiple versions, remove the extra Office installation and keep only the one tied to the license.
- Check subscription or license status
- If the subscription expired, Office can become Unlicensed Product.
- Confirm the license or subscription is still active.
- Use the Update License button
- In Word, Excel, or PowerPoint, go to File > Account.
- Under Product Information, select Update License.
- This refreshes the device license.
- If Couldn't update license with Error Code: 44 appears, the app is usually signed in with an account that does not have the license.
- Check date, time, and time zone
- Close all Office apps.
- Select the date/time in the bottom-right corner of Windows.
- Open Date and time settings.
- Turn on Set time automatically and, if available, Set time zone automatically.
- Restart an Office app.
- Run Office as administrator
- Close all Office apps.
- Open Start, type Word or Excel.
- Right-click the app and select Run as administrator.
- Select Yes.
- Update Office
- Open any Office app.
- Go to File > Account.
- Under Product Information, select Update Options > Update Now.
- If needed, select Enable Updates first.
- If Office apps still fail, do an Online Repair
- In Windows, open Settings > Apps.
- Find Microsoft Office.
- Select it, choose Modify, then run Online Repair.
- This is more complete than the quick repair shown in the error dialog.
If the problem started after installing another Office version, remove the extra version first because multiple installs can block activation.
