A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
Try these steps in order:
- If the error says "Can't read file" or "Presentation cannot be opened", the file may be blocked by Microsoft 365:
- Open File Explorer.
- Find the PowerPoint file.
- Right-click it and select Properties.
- If Unblock appears near the bottom, select Unblock > Apply > OK.
- Try opening the file again.
- If PowerPoint says it can't open this file, try opening another copy of the file.
- If it came from email, ask for the file to be sent again.
- If it came from a disk or external source, try another copy.
- This can indicate a file format problem or file corruption.
- If the file is very old, check whether it is a PowerPoint 95 file.
- PowerPoint 2007 and later cannot open presentations saved as PowerPoint 95.
- Open the file in PowerPoint 2003, 2002, 2000, or 97.
- Select File > Save As.
- In Save as type, choose Presentation (*.ppt), then save it.
- Open the new file in a newer PowerPoint version.
- If PowerPoint itself is not opening or is hanging, start it in Safe Mode to check for add-in problems:
- Press Start and type
powerpnt /safe. - If PowerPoint opens in Safe Mode, go to File > Options > Add-Ins.
- Select COM Add-ins > Go.
- Clear the add-in checkboxes, select OK, and restart PowerPoint.
- Re-enable add-ins one at a time to find the one causing the issue.
- Press Start and type
- Repair Office if PowerPoint still does not open:
- Close all Office apps.
- Open Control Panel > Programs and Features.
- Right-click Microsoft Office or Microsoft 365.
- Select Change > Repair.
- If the error specifically says "PowerPoint could not open the file" or "No text converter", that usually indicates file corruption. Use the repair guidance in Open a document after a file corruption.
If the problem is only with one presentation, focus on file unblock/corruption steps. If PowerPoint itself will not launch, focus on Safe Mode, add-ins, and Office repair.
