    @Alex W
    Hi,
    Open command prompt as administrator type
    sfc scannow
    then
    dism /online /cleanup-image /restorehealth

    Have you tried Uninstalling Office 2010 & then Reinstalling it?
    If do try the Unistall & Reinstall method, it is best to shut down & restart the computer after uninstalling before reinstalling.
    Hope above information can help you.
