Dear Nice Pti4ka,
Good day! Thank you for posting to Microsoft Community. We are happy to help you
First I would like to confirm what is the operating system of the device you are using.
If you are using Windows, try the following suggestions first: Go to Control Panel -> Programs -> right-click on Office applications’ icon -> Change -> Online Repair.
We look forward to your reply. Thanks for your cooperation.
Sincerely,
