How to Resolve PowerPoint ‘Microsoft Office Has Stopped Working’

You are working in PowerPoint when the application freezes and you see the error message “Microsoft Office Has Stopped Working.” This error usually occurs due to a conflict between PowerPoint and an add-in, a corrupted file in the user profile, or an issue with hardware graphics acceleration. This article explains why the error happens and provides step-by-step fixes to get PowerPoint running again.

Why PowerPoint Shows the “Microsoft Office Has Stopped Working” Error

PowerPoint crashes with this error when a component inside the application fails unexpectedly. The most common trigger is a third-party add-in that conflicts with PowerPoint’s code. Add-ins from PDF converters, screen recorders, or older Office versions often cause this problem.

Another frequent cause is hardware graphics acceleration. PowerPoint uses your computer’s GPU to render animations and transitions. If the GPU driver is outdated or incompatible, PowerPoint stops working during slide shows or when applying effects.

Corrupted user profile settings or damaged Office installation files can also produce this error. The error message does not tell you which component failed, so you must test each fix in order.

Steps to Fix the “Microsoft Office Has Stopped Working” Error

Step 1: Start PowerPoint in Safe Mode

1. Close all open PowerPoint windows
   Press Ctrl+Alt+Delete and select Task Manager. Under Processes, right-click PowerPoint and choose End Task.
2. Press and hold the Ctrl key
   While holding Ctrl, double-click the PowerPoint icon on your desktop or Start menu.
3. Release Ctrl when prompted
   A dialog box asks if you want to start PowerPoint in Safe Mode. Click Yes.

If PowerPoint opens in Safe Mode without the error, an add-in is causing the crash. To disable the problematic add-in:

1. Go to File > Options > Add-ins
   At the bottom of the dialog, next to Manage, select COM Add-ins from the dropdown and click Go.
2. Uncheck all add-ins
   Clear every checkbox to disable all COM add-ins. Click OK.
3. Restart PowerPoint normally
   Close PowerPoint and reopen it without holding Ctrl. If the error is gone, re-enable add-ins one by one to find the offender.

Step 2: Disable Hardware Graphics Acceleration

1. Open PowerPoint
   If you are unable to open PowerPoint at all, start it in Safe Mode using the Ctrl key method from Step 1.
2. Go to File > Options > Advanced
   Scroll down to the Display section.
3. Check the box labeled “Disable hardware graphics acceleration”
   This forces PowerPoint to use your CPU instead of the GPU for rendering.
4. Click OK and restart PowerPoint
   Close and reopen the application to apply the change.

Step 3: Repair Your Office Installation

1. Open Control Panel
   Press Windows + R, type control, and press Enter.
2. Go to Programs > Programs and Features
   Find Microsoft 365 or Microsoft Office in the list.
3. Right-click the entry and select Change
   Choose Quick Repair and click Repair. Windows will fix corrupted files without removing your data.
4. If Quick Repair fails, run Online Repair
   Return to the same screen and select Online Repair. This requires an internet connection and takes longer.

Step 4: Clear the Office User Profile Cache

1. Close all Office applications
   Ensure PowerPoint, Word, and Excel are not running.
2. Press Windows + R, type %appdata%, and press Enter
   This opens the AppData\Roaming folder.
3. Navigate to Microsoft\Office
   Look for a folder named 16.0 (or 15.0 for older versions).
4. Delete the folder named OfficeFileCache
   If you do not see this folder, skip this step. Restart PowerPoint.

If PowerPoint Still Crashes After the Main Fix

PowerPoint Crashes Only in a Specific Presentation

The presentation file itself may be corrupted. Open PowerPoint in Safe Mode, then go to File > Open > Browse. Select the file and click the arrow next to Open. Choose Open and Repair. PowerPoint attempts to fix the file automatically.

Error Appears After a Windows Update

A recent Windows update may have changed a system file that Office depends on. Go to Settings > Windows Update > Update history > Uninstall updates. Remove the most recent update and restart your computer. Then run the Office repair from Step 3.

PowerPoint Shows the Error on a Shared or Network Drive

PowerPoint may stop working if it cannot write temporary files to the network location. Copy the presentation to your local desktop, open it from there, and save a copy to the network after editing.

PowerPoint Safe Mode vs Normal Mode: Key Differences

Item	Safe Mode	Normal Mode
Add-ins loaded	None — all add-ins are disabled	All enabled add-ins load on startup
Hardware acceleration	Disabled automatically	Enabled unless user changes settings
Toolbar customizations	Not loaded — default ribbon shown	All custom toolbars and ribbons appear
File templates	Normal template is not loaded	Default templates and themes are applied

After applying the fixes above, you can now open PowerPoint without seeing the “Microsoft Office Has Stopped Working” error. Start by testing Safe Mode to identify add-in conflicts, then disable hardware acceleration if the error persists. As a final step, run the Office repair tool to restore any damaged system files. If you frequently work with complex presentations, consider keeping hardware acceleration disabled to avoid future crashes during slide transitions.
