Hi @Nethuli Thihansa

Thank you for posting your question in the Microsoft Q&A forum.

I have moved the photo to the Private message if you need to add any more privacy information please add it in there.

 

Regarding your issue, may I kindly ask a few questions so I can understand your issue better:  

• I saw that you posted your question for Excel under the Education category so to better support you, could you confirm what type of Microsoft subscription are you using?
• Could you let me know what happens after you click Repair? Does it help fix the issue? 
• Were you previously able to use the Office desktop or were you only using Office on the web?

Hope to hear back from you soon.  

The initial response may not fully address your needs, but it will help me better understand your situation. Once I get the information, I will try my best to find the next steps.

Answer 2

The error dialog in the screenshot is the generic “has run into an error” message, and the built‑in “Repair now” option often does not fix it. Use a full Online Repair of Office instead, which reinstalls the Office apps and usually resolves problems affecting Word, Excel, and PowerPoint together.

Steps:

1. Close all Office apps (Word, Excel, PowerPoint, etc.).
2. Run an Online Repair of Office by following the steps in the “Repair an Office application” article (choose the Online Repair option, not Quick/Repair Now). This will reinstall Office and fix most app‑level issues.
3. After the repair completes, restart Windows and try opening the same PowerPoint, Excel, and Word files again.

If the problem persists after a full Online Repair, further registry‑level troubleshooting may be required, which is typically handled by Microsoft Support.
