Run an Online Repair of Microsoft 365 or Office first, because it repairs the entire Office installation when Excel cannot start correctly.

1. Run Online Repair

Close Excel and all other Office applications, then:

Windows 11

Right-click Start and select Installed apps.
Find Microsoft 365 or Microsoft Office.
Select the three dots beside it, then Modify.
Select Online Repair → Repair.
Follow the prompts, restart the computer when finished, and open Excel.

Windows 10

Right-click Start and select Apps and Features.
Select Microsoft 365 or Microsoft Office, then Modify.
Select Online Repair → Repair.
Complete the repair, restart Windows, and test Excel.

Online Repair is more thorough than Quick Repair. It repairs the whole Office suite even if only Excel is affected.^1^

2. If the error remains, test Excel without add-ins

Press Windows key + R.
Enter:

excel /safe

Select OK.

Safe Mode bypasses Excel and most COM add-ins, startup folders, and certain customized settings.^2^

If Excel opens successfully in Safe Mode:

Go to File → Options → Add-ins.
At the bottom, choose COM Add-ins from Manage, then select Go.
Clear every checkbox and select OK.
Close Excel and start it normally.
If it now works, re-enable add-ins one at a time, restarting Excel after each one, to identify the conflicting add-in.

3. If Online Repair and Safe Mode both fail

Uninstall and reinstall Microsoft 365 or Office. Microsoft recommends its uninstall troubleshooter for Microsoft 365 and Office 2021, 2019, or 2016; it must be run on the affected Windows 10 or later PC. After uninstalling, restart the computer and reinstall Office from the Microsoft account associated with the licence.^3^

Before uninstalling, confirm that important workbooks are saved somewhere safe. Uninstalling Office normally does not remove documents, but keeping a backup is recommended.

Hi Arivumathi, 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.

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.
