Observed behavior
Office blocks the language pack installation with an error stating that another update is in progress, even when no updates are visibly running and after the computer is restarted.

Solution 1Recommended

Force Complete Any Pending Office Updates

Manually triggering the update process can resolve stuck background updates that are blocking the language pack installation.

Often, the Office Click-to-Run service gets stuck attempting a silent background update. Forcing the application to check for and install updates will clear the queue.

1
Open an Office Application

Launch Microsoft Word or Excel to access the account settings.

2
Navigate to Update Options

Click on 'File' in the top ribbon, select 'Account' from the left sidebar, and look for the 'Update Options' button.

3
Update Now

Click 'Update Options' and select 'Update Now'. Wait for the process to complete, close all Office apps, and then retry installing your language pack.

Force Complete Any Pending Office Updates
Restart Required: Once the manual update says 'You're up to date!', make sure to completely close all Office windows before trying the language pack again.

Frequently Asked Questions

How do I check if my Office installation is 32-bit or 64-bit?

Open any Office application like Word or Excel. Click on 'File' > 'Account', and then click the 'About Word' (or Excel) button. The architecture (32-bit or 64-bit) will be displayed at the very top of the informational window.

Why does Office say an update is installing when nothing is visible?

Microsoft Office uses a background service called Click-to-Run for silent updates. Sometimes this service gets stuck or encounters an error, making the system think an update is perpetually in progress. Forcing a manual update or restarting the Click-to-Run service usually clears this state.

Can having multiple versions of Office cause language pack errors?

Yes. If you have remnants of an older Office version (like Office 2016 alongside Microsoft 365), the language pack installer might get confused about which directory or architecture to target. It is highly recommended to uninstall older, unused versions via the Windows Control Panel.
