I am not able to open any office 360 app, with message that it has run into an error that is preventing it from working correctly. It will need to be closed as a result. It gives options as Repair now, Help and Close. Even after choosing Repair now, nothing happens.

Please help resolve.

On Windows, run Online Repair from Windows Settings instead of selecting Repair Now in the error dialog, because the full repair applies to the entire Microsoft 365 suite.

Run a full Online Repair

Since the repair button in the popup did nothing, use the Windows repair interface:

Windows 11

  1. Right-click Start and select Installed apps.
  2. Find Microsoft 365 or Microsoft Office.
  3. Select the three dots (…) beside it, then select Modify.
  4. If prompted by User Account Control, select Yes.
  5. Select Online Repair → Repair.
  6. Allow the process to finish, restart the computer, and open Word or Excel.

Windows 10

  1. Right-click Start and select Apps and Features.
  2. Select Microsoft 365 or Microsoft Office, then select Modify.
  3. Select Online Repair → Repair.
  4. Complete the repair, restart the computer, and test an Office application.

Online Repair is the more thorough option and repairs the whole suite, even when launched for one application.^1^ This is also the recommended resolution for the same error when the popup’s Repair Now option does not work.^2^

If Online Repair does not resolve it

Completely remove and reinstall Microsoft 365:

  1. Open Microsoft’s startup-error support page and run the uninstall troubleshooter.
  2. When prompted, allow it to open Get Help.
  3. Complete the removal and restart the PC when requested.
  4. Sign in to the Microsoft 365 Apps page using the Microsoft, work, or school account associated with the license.
  5. Select Install apps and install Microsoft 365 apps.
  6. Open Word and complete any activation prompt.

The uninstall troubleshooter must run on the affected PC and requires Windows 10 or later. It currently cannot uninstall Office 2024.[^3^](https://support.microsoft.com/office/lifecycle/something-went-wrong-error-when-you-try-to-start-a-microsoft-365-app ""Something went wrong" error when you try to start a Microsoft 365 app | Microsoft Support") Microsoft documents the account sign-in, download, installation, and activation process here.^4^

If Microsoft 365/Office is not listed under Installed apps, or Modify is unavailable, use Control Panel → Programs → Programs and Features, right-click the Microsoft 365 product, and select Change or Repair.[^3^](https://support.microsoft.com/office/lifecycle/something-went-wrong-error-when-you-try-to-start-a-microsoft-365-app ""Something went wrong" error when you try to start a Microsoft 365 app | Microsoft Support")
