POWER POINT CLOSING

Try these steps in order to fix PowerPoint closing when choosing “Repair now”:

1. Run a full Online Repair of Office
   1. Close all Office apps.
   2. Open Control Panel → Programs and Features.
   3. Select Microsoft Office (or Microsoft 365 Apps), choose Change.
   4. Select Repair (preferably the full/online repair option, not just Quick Repair) and let it complete.
   5. Restart Windows and test PowerPoint again.
2. Check antivirus integration
   1. Make sure antivirus is fully updated.
   2. If the antivirus has Office/PowerPoint integration or add‑ins, temporarily disable that integration or those add‑ins.
   3. Restart and test PowerPoint.
   Note: Changing antivirus settings can increase security risk; only do this if comfortable and re‑enable protection afterwards.
3. Change the default printer
   1. Open Control Panel → Hardware and Sound → Devices and Printers.
   2. Right‑click Microsoft XPS Document Writer or Send to OneNote.
   3. Click Set as default printer.
   4. Start PowerPoint and try opening a presentation.

If PowerPoint still crashes after these steps, completely uninstalling Office (including leftover folders and registry entries) and then reinstalling, as described in the Q&A references, is often required to clear a corrupted installation.
