    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 or Apps and Features

    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 a full repair of the Microsoft 365 or Office installation, using Online Repair for Click-to-Run installations or Repair for MSI-based installations.

    1. Repair Office

    1. Close Word, Excel, and PowerPoint.
    2. Open the repair settings:
      • 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 or select the product, and then choose Modify.
    5. Use the option shown:
      • If the window says How would you like to repair your Office Programs?, select Online Repair → Repair. This is the Click-to-Run installation type.
      • If the Change your installation window appears instead, select Repair → Continue. This is an MSI-based installation.
    6. Complete the repair, restart Windows if requested, and test all three applications.

    The repair applies to the entire Office suite, even when initiated for only one application.^1^

    2. If repair does not work, test add-ins

    Start each application in Office Safe Mode:

    1. Press Windows key + R.
    2. Enter one command at a time:
      • Word: winword /safe
      • Excel: excel /safe
      • PowerPoint: powerpnt /safe
    3. If an application opens in Safe Mode, select File → Options → Add-ins.
    4. At the bottom, select COM Add-ins from Manage, and then select Go.
    5. Clear one add-in, select OK, close the application, and launch it normally.
    6. Repeat with the next add-in until the application opens normally. Leave the problematic add-in disabled or obtain an updated version from its publisher.

    If an application cannot start in Safe Mode, add-ins are unlikely to be the problem; proceed to reinstalling Office.^2^

    3. If both steps fail, uninstall and reinstall Office

    Before uninstalling, confirm that the Microsoft account associated with Office shows the correct subscription or licence at Microsoft account Services.^3^

    Then:

    1. On the affected PC, open the Microsoft Office uninstall troubleshooter.
    2. Select Open when prompted to open Get Help.
    3. Complete the prompts and restart Windows.
    4. Reinstall Office using the associated Microsoft account or your installation licence.

    Uninstalling Office removes the applications but does not remove documents, spreadsheets, or presentations created with them.^4^

    The uninstall troubleshooter requires Windows 10 or later and currently cannot uninstall Office 2024. If you have Office 2024, uninstall it through Settings → Apps → Installed apps instead.^5^
