PowerPoint slides are not opening.

Question

PowerPoint slides are not opening.

NAAVYA A/P KRISHNA KUMAR 0

"We're sorry, but PowerPoint has run into an error that is preventing it from working correctly. PowerPoint will need to be closed as a result. Would you like us to repair now?"

When I chose the "Repair Now" button, it does not work at all and I still cannot access my slides. What is happening here?

Hello @NAAVYA A/P KRISHNA KUMAR,

Please do the following step:

Try online repair option:

Exit all Office apps.
Then run the online repair. Please follow the guidance here: https://support.microsoft.com/en-us/office/lifecycle/repair-an-office-application

User's image

Try open in safe mode:

Right-click the Start button (lower-left corner) in Windows, and click Run.
For PowerPoint: Type powerpnt /safe, and click OK. For reference, please visit: https://support.microsoft.com/en-us/office/lifecycle/open-office-apps-in-safe-mode-on-a-windows-pc

If these steps do not work, please confirm:

Does the issue occur with one specific PowerPoint file or all PowerPoint files?
Does the same issue occur in other Office applications, such as Word or Excel?
Does the issue occur with a new blank PowerPoint presentation?
Kindly share me a screenshot of this issue.

Thank you for your patience and understanding

Run an Online Repair of Microsoft 365 from Windows Settings; the Repair Now action in the error dialog has already failed, while Online Repair performs the more thorough suite-wide repair.

Run the full repair

Close all 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.
Complete the prompts and restart Windows if requested.

Windows 10

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

Online Repair repairs the entire Office suite, even when only PowerPoint is failing. If the installer instead displays Change your installation, the installation is MSI-based; select Repair → Continue. ^1^

Afterward, start PowerPoint directly and then open a presentation. The expected result is that PowerPoint launches without the error and the slides open normally.

If PowerPoint still will not open

Test whether a PowerPoint add-in is preventing startup:

Press Windows key + R.
Enter:

powerpnt.exe /safe

Select OK.
If PowerPoint opens in Safe Mode, go to File → Options → Add-ins.
Beside Manage, select COM Add-ins → Go.
Clear every add-in checkbox, select OK, and restart PowerPoint normally.
If it now works, re-enable add-ins one at a time, restarting PowerPoint after each one, until the problem returns. Leave the conflicting add-in disabled. ^2^

If PowerPoint cannot start even in Safe Mode after Online Repair, this is no longer isolated by the available procedures. On an education-managed computer, contact the school’s IT administrator to repair or redeploy the Microsoft 365 installation; otherwise, proceed to Microsoft Support.
