    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.

    1

    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.

    If that does not resolve the problem, are you seeing any notification at the bottom right of your screen indicating Smart App Control security is blocking Office.

    Run an Online Repair of Microsoft Office because both Word and Excel are failing; this repairs the entire Office suite rather than only the application shown in the error dialog.^1^

    Run Online Repair

    1. Close Word, Excel, Outlook, and all other Office applications.
    2. Open the repair screen:
      • Windows 11: Right-click Start → Installed apps.
      • Windows 10: Right-click Start → Apps and Features.
    3. Find Microsoft 365 or Microsoft Office.
    4. Select the three dots (if displayed) → Modify.
    5. For the common Click-to-Run installation, select Online Repair → Repair.
      • Do not select Quick Repair; Online Repair performs the more complete repair.
      • If the installer instead displays an MSI-based Change your installation screen, select Repair → Continue.
    6. Complete the on-screen instructions and restart Windows.
    7. Open Excel and Word and confirm that both start normally.

    Microsoft’s repair procedure applies to the entire suite even when only Word or Excel is selected.^1^

    If Online Repair does not fix it

    Test each application in Office Safe Mode:

    1. Press Windows key + R.
    2. Enter the following command for Excel:
    excel /safe
    1. Repeat with this command for Word:
    winword /safe

    Safe Mode bypasses most add-ins and custom startup components. If an application works only in Safe Mode, open it in Safe Mode and go to:

    File → Options → Add-ins → Manage: COM Add-ins → Go

    Clear the enabled add-ins, close the application, and start it normally. Re-enable add-ins individually afterward to identify the one causing the startup failure.^2^

    If neither Word nor Excel opens even in Safe Mode after Online Repair, report the Windows version, Office edition, and whether Modify offered Click-to-Run or MSI repair options; those details are needed to select the next supported recovery path.
