Dear @Pratima Tiwari,
Based on your description, if Microsoft PowerPoint keeps showing "Repairing..." every time you open it, the issue is usually caused by a damaged Office installation, add-ins, user profile corruption, or Office update problems.
Here are some suggestions you can try:
Check if PowerPoint works in Safe Mode
- Press Windows + R
- Type:
powerpnt /safe - Press Enter
If PowerPoint opens normally in Safe Mode, an add-in is likely causing the issue.
To disable add-ins:
- Open PowerPoint
- Go to File > Options > Add-ins
- At the bottom, select COM Add-ins and click Go
- Uncheck all add-ins
- Restart PowerPoint normally
Try online repair
A Quick Repair sometimes does not fully fix corruption.
- Close all Office apps
- Open Control Panel
- Go to Programs and Features
- Select Microsoft 365 or Office
- Click Change
- Choose Online Repair
- Complete the repair and restart Windows
Reset the PowerPoint User Profile
- Close PowerPoint
- Press Windows + R
- Type:
regedit - Navigate to:
HKEY_CURRENT_USER\Software\Microsoft\Office - Rename the folder matching your Office version: 16.0 = Microsoft 365 / Office 2019 / Office 2021
Example: 16.0 -> 16.0_old
Reopen PowerPoint > This resets PowerPoint settings without affecting your presentation files.
Check for Corrupted Templates
- Close PowerPoint
- Browse to:
%appdata%\Microsoft\Templates - Rename:
(if present)Blank.potx - Restart PowerPoint
If you have tried all the method above but the issue still persists, please try to uninstall then reinstall again.
In the meantime, it would be helpful if you could provide the exactly error message of the issue so I can support you more effectively.
Looking forward to your update.
