    Run an Online Repair of Microsoft Office from Windows 11 rather than relying only on the Repair Now button in the Excel error dialog.

    Repair Office

    1. Close Excel, Word, Outlook, and all other Office applications.
    2. Right-click Start and select Installed apps.
    3. Find Microsoft 365 or Microsoft Office.
    4. Select the three dots (…) beside it, then select Modify.
    5. If the installation uses Click-to-Run, select Online Repair → Repair.
      If it is MSI-based, select Repair → Continue.
    6. Allow the repair to finish, restart the computer, and then open Excel.

    Online Repair repairs the entire Office installation, even when only Excel is failing. It is more comprehensive than Quick Repair and may require an Internet connection and subsequent Office sign-in or activation.^1^

    If Excel still displays the error

    Test whether an Excel add-in is responsible:

    1. Press Windows key + R.
    2. Enter the following command, including the space:
    excel /safe
    1. Select OK. The title bar should show Microsoft Excel (Safe Mode).
    2. If Excel opens, go to File → Options → Add-ins.
    3. At the bottom, select COM Add-ins under Manage, then select Go.
    4. Clear the add-in checkboxes and restart Excel normally.
    5. Re-enable add-ins individually, restarting Excel each time, to identify the problematic one.^2^

    If Excel does not open in Safe Mode and Online Repair does not resolve it, the documented next steps are to install Windows/driver updates and then uninstall and reinstall Office.^2^

    Hi, this seems to be an ongoing bug with the Office apps for a couple of days which may be caused by an update, there are many people reporting this problem.

    The 'Repair Now' button on that error popup dialog only performs a quick repair of the Office apps and that rarely resolves the problem with the Office apps, the best option is to perform a full online repair of your Office installation.

    Before performing this process to ensure you do not loose the Office installation during the repair, please log into your Microsoft account on this link (https://account.microsoft.com/services/) and check to ensure your Office licence or Microsoft 365 subscription is listed correctly on your account.

    Open the Settings App (gear icon on your Start Menu)

    Go to Apps - Installed Apps.

    Then, scroll down to find Microsoft Office or Microsoft 365.

    Select that and choose Modify - Online Repair

    That should fix any issues with your Office Installation.
