    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

    Select that and choose Modify - Online Repair

    That should fix any issues with your Office Installation.

    If that does not resolve the problem, completely uninstall Office, restart your PC, then download and reinstall Office from your account online (https://account.microsoft.com/services/).

    Run an Online Repair of Microsoft 365 or Office rather than relying on the Repair Now button in the PowerPoint error dialog.

    Run Online Repair

    1. Close PowerPoint 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, Microsoft Office, or standalone PowerPoint.
    4. Select the three dots or the application, and then select Modify.
    5. If prompted for administrator permission, select Yes.
    6. For a Click-to-Run installation, select Online Repair → Repair.
      If only an MSI repair option appears, select Repair → Continue.
    7. Complete the process, restart Windows if prompted, and open PowerPoint again.

    Online Repair is more comprehensive than Quick Repair and repairs the entire Office suite, even when only PowerPoint is failing.[^1^](https://support.microsoft.com/office/-something-went-wrong-error-when-you-try-to-start-a-microsoft-365-app-4b4471dd-cf86-4a37-910d-35a01a6c7d17 ""Something went wrong" error when you try to start a Microsoft 365 app") The same procedure resolved matching cases where the error-dialog repair did not work.^2^

    If PowerPoint still fails

    Test whether an add-in is preventing startup:

    1. Press Windows key + R.
    2. Enter: 
         powerpnt /safe
    3. Select OK.
    4. If PowerPoint opens and its title bar shows Safe Mode, go to: File → Options → Add-ins.
    5. At the bottom, choose COM Add-ins under Manage, then select Go.
    6. Clear all add-in checkboxes and restart PowerPoint normally.
    7. If it works, re-enable add-ins one at a time, restarting PowerPoint after each one, to identify the incompatible add-in.[^3^](https://support.microsoft.com/office/lifecycle/i-get-a-stopped-working-error-when-i-start-office-applications-on-my-pc "I get a "stopped working" error when I start Office applications on my PC | Microsoft Support")

    If PowerPoint does not open in Safe Mode, the problem is not caused by add-ins. After Online Repair, Microsoft’s next documented paths are to update Windows and device drivers, then uninstall and reinstall Office if the failure continues.[^3^](https://support.microsoft.com/office/lifecycle/i-get-a-stopped-working-error-when-i-start-office-applications-on-my-pc "I get a "stopped working" error when I start Office applications on my PC | Microsoft Support")
