If I may add to Mr Balkan's comment. Before you do a new installation, go to the "Control Panel" and do an Office repair. Otherwise, please follow Mr. Baklan's instructions step by step.

Microsoft Office: Repair Tips for Windows

To repair the Office Click-to-Run application, follow these steps as appropriate for the version of Windows that the computer is running.

Windows 10, Windows 8.1 and Windows 8:

1. On the Windows Start screen, type Control Panel.
2. Click or tap Control Panel.
3. Under Programs, click or tap Uninstall a program.
4. Click or tap MicrosoftOffice 365, and then click or tap Change.
5. Click or tap QuickRepair, and then click or tap Repair. You may have to restart your computer after the repair process is complete. 

To repair Microsoft Office using on-board tools, first open the Control Panel.

    Click on Apps and Functions / Features in the pop-up menu, then select Microsoft Office.

    To do this, click on "Change". The entire Office suite will now be repaired. If you only want to repair a single application such as Word, look for the specific name of the app.

    If you are using Windows 7, Vista or 8, click in the Control Panel on "Category", then on "Programs" and then select "Uninstall a program". With a click of the right mouse button on the program to be repaired, you can select the option "Change".

More options for Click-to-Run and MSI-based applications

    If you have the Click-to-Run version, select "Online repair" when asked "How would you like to repair your Office programs?" Confirm your selection by clicking on "Repair". The quick repair is only recommended to a limited extent, as it may not detect all errors.

    If you are using an MSI-based version, click on “Repair” under “Change installation”. Confirm the process by clicking on "Next".

    If this does not help, you may have to reinstall your Microsoft Office.

Thank you everyone for your patience and time
