    Hello @Laura Santee

    1. Please try to download and Install manually KB2604115 from Microsoft catalog website.
    2. Disable any Antivirus program or Windows firewall you may have for temporary purpose
    3. Cleanup below Temp folders
      C:\Windows\Temp
      %USERPROFILE%\AppData\Local\Temp

    Please also have a look on below Microsoft thread for further troubleshooting steps.
