    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.

    Start Excel in Safe Mode with excel /safe; if it opens, disable its add-ins, and if it does not open, repair the Microsoft 365 installation.

    1. Test Excel in Safe Mode

    1. Press Windows key + R.
    2. Enter:
         excel /safe
      
    3. Select OK.

    The Excel title bar should display Microsoft Excel (Safe Mode). Safe Mode bypasses add-ins and several startup customizations that can stop Excel from opening normally.^1^

    If Excel opens in Safe Mode:

    1. Go to File → Options → Add-ins.
    2. At the bottom, select COM Add-ins from Manage, then select Go.
    3. Clear all checkboxes and select OK.
    4. Close Excel and start it normally.
    5. If Excel now works, re-enable add-ins one at a time, restarting Excel after each one, until the faulty add-in is identified.^1^

    Also repeat this process for Excel Add-ins if that option appears in the Manage list.

    2. If Safe Mode fails, repair Microsoft 365

    Close every Office application before starting. Repair applies to the entire Office suite, even when only Excel is affected.^2^

    Windows 11

    1. Right-click Start → Installed apps.
    2. Find Microsoft 365 or Microsoft Office.
    3. Select the three dots → Modify.
    4. For a Click-to-Run installation, select Online Repair → Repair.
    5. Complete the prompts and restart Windows.

    Windows 10

    1. Right-click Start → Apps and Features.
    2. Select Microsoft 365 or Microsoft Office → Modify.
    3. Select Online Repair → Repair.
    4. Complete the repair and restart Windows.

    Online Repair is more complete than Quick Repair. If the installer instead displays an MSI-based repair window, select Repair → Continue.^2^

    3. If Excel remains blocked

    If another Office application opens, use File → Account → Update Options → Update Now to install Office updates. If repair and updates do not resolve the failure, uninstall and reinstall Microsoft 365 or Office. Microsoft recommends reinstalling when the application cannot start even in Safe Mode and repair does not correct it.^3^

    Before uninstalling, ensure that the Microsoft account and installation details used for the original Office installation are available. Uninstalling removes the Office applications, so save and close any open documents first.
