POWERPOINT MICROSOFT 365 DOESN'T WORK

Question

POWERPOINT MICROSOFT 365 DOESN'T WORK

LAM THI NHU Y 0

When I open Microsoft PowerPoint, a message appears asking me whether I want to start the application in Safe Mode. However, when I click "Yes," one of the following two situations occurs:

PowerPoint opens, but it automatically closes after I click a few times (approximately three clicks).

PowerPoint fails to open at all.

In both cases, PowerPoint does not display any error messages or provide an explanation for why it stops working.

I have already tried both the "Quick Repair" and "Online Repair" options, but the problem persists. User's image

Hi @LAM THI NHU Y,

At this point, I would recommend having the device examined by a trusted computer repair technician or local computer service center. They can perform more advanced diagnostics on Windows system files, user profiles, hardware, and other software conflicts that may not be easily identified through standard Office troubleshooting.

Additionally, if you are using a school or educational Microsoft 365 account, I recommend contacting your school's IT support team. They may be able to check for organization-specific policies, licensing issues, or device management settings that could be contributing to the problem.

Hopefully they can identify the root cause and get PowerPoint working properly again.

Hello @LAM THI NHU Y,

I'm sorry to hear that PowerPoint is not working as expected.

To help provide the most accurate and effective solution, could you please share a bit more information about your environment?

What version of Windows are you using (Windows 10 or Windows 11)?
Are other Microsoft 365 applications, such as Word and Excel, working normally?
Does PowerPoint crash when opening a blank presentation, or only when opening specific files?
Have there been any recent changes to your device, such as Windows updates, Office updates, or new software installations?
As you mentioned that you have already tried both Quick Repair and Online Repair, may I confirm whether these were performed through Control Panel > Programs and Features > Microsoft 365 > Change?

This additional context will help us better understand your environment and determine the root cause of the issue.

In the meantime, please try the following steps to open PowerPoint in Safe Mode manually:

Before performing any troubleshooting steps, I recommend backing up all important data to a secure location to prevent any potential data loss.

Open PowerPoint in Safe Mode by pressing Windows + R, type: powerpnt /safe
If PowerPoint opens in Safe Mode, disable any add-ins: File > Options > Add-ins > Manage COM Add-ins > Uncheck all > OK.

Close PowerPoint and launch it normally to check whether the issue persists.

If the issue persists, please also try:

Open PowerPoint in Safe Mode again.
Navigate to File > Options > Advanced.
Under Display, check Disable Slide Show hardware graphics acceleration.

Restart PowerPoint and test again.

Looking forward to your response so we can investigate this further and get PowerPoint working properly again.

Kind regards,

Thank you so much for sharing your suggestions.

First, let me answer your questions:

My operating system is Windows 11.

Other Microsoft 365 applications, such as Word and Excel, are working normally.

PowerPoint crashes even when I try to open a blank presentation. I also cannot open any existing files. PowerPoint prompts me to start in Safe Mode, but when I click "Yes," nothing happens. PowerPoint either stops responding or closes without displaying any error messages.

Windows and Office are both up to date, and I haven't installed any new software recently.

I followed these steps: Control Panel > Programs and Features > Microsoft 365 > Change.

I also tried the following procedure, but PowerPoint kept crashing:

File > Options > Add-ins > Manage COM Add-ins > Uncheck all > OK.

Now, I cannot click anything in PowerPoint, so I am unable to try your suggestion to go to Display and check "Disable Slide Show hardware graphics acceleration."

Thank you again for your help.

Kind regards,

Hello @LAM THI NHU Y,

Thank you for the detailed information.

Since the issue persists in Safe Mode, this may indicate a problem beyond normal add-ins. I'd like to suggest a few additional troubleshooting steps.

1. Check for Windows or Office updates

Press Windows + I to open the Settings app.

Windows Update and install any pending updates.

Open any Office app that still works normally, go to File > Account > Update Options > Update Now.

2. Change the default printer

Microsoft's documentation notes that PowerPoint can sometimes encounter startup issues related to the default printer configuration.

Open the Control Panel, and then open Hardware and Sound using this link: Control Panel\Hardware and Sound\Devices and Printers

In the list of printers, right click on either the Microsoft XPS Document Writer or Send to OneNote.

Select Set as default printer from the menu.

3. Reinstall Office

If the problem persists, try reinstalling Office after uninstalling it. You can follow Microsoft's office guide:

Uninstall Office: Uninstall Microsoft 365 or Office from a PC | Microsoft Support

Restart your computer.

Install Office: Download, install, or reinstall Microsoft 365 or Office 2024 on a PC or Mac | Microsoft Support

Please let me know whether these steps resolve the issue, and I’ll be happy to assist you further. Thank you for reaching out!
