    Hi,

    Do you have any third-party customization software installed, such as WindowBlinds or theme packs?

    If so, you can either uninstall the software or add the Office folder to the software's exclusion list. Then, go to Control Panel > Programs > Microsoft Office > ... > Change > Online Repair.

    Thanks.
