Hello Sushil,
One possible reason why this message appears is because Office has not yet been activated. To better assist you and provide you with the appropriate troubleshooting steps, kindly answer the questions below:
- Does this error come up on all documents you try to open?
- Is Office 365 activated? To check, click on File and select Account on any Office 365 application.
- Can you post a screenshot of the error message that you are getting?
We're looking forward for your response
