Hi,
There are different possible reasons that can cause this issue. One of these is a corrupted program file. Sometimes restarting your device fixes the issue.
If restarting doesn't fix it, we can still proceed to repair the program.
Here are the steps:
- Right-click the Start button
(lower-left corner), and select
Apps and Features on the pop-up menu. - Select the Microsoft Office product you want to repair, and select Modify.
- Depending if your copy of Office is Click-to-run or MSI-based install, do the following.Click-to-run: In How would you like to repair your Office Programs, select Online Repair to make sure everything gets fixed, and then select Repair. (The faster Quick Repair option is also available, but it only detects and then replaces corrupted files.)**MSI-based:**In Change your installation, select Repair and then click Continue.
- Follow the instructions on the screen to complete the repair.
Let us know how it goes so that we can further assist you.
