FAQ: How do I resolve an OfficeConnect Update Error?
When updating OfficeConnect, you can receive the following error message:
"An error occurred while downloading the update. Details: The underlying connection was closed: An unexpected error occurred on a send."
You can encounter this error if:
- Your connection or network has blocked the update from completing. Work with your IT team to ensure your network supports this update. You can also download a troubleshooting tool. See Troubleshooting Tool: OfficeConnect and Planning for Excel.
- You're running Windows 7 and an older version of Transport Layer Security (TLS). Between 2017 and 2019, we dropped support for TLS 1.0 and 1.1. Work with your IT team to enable TLS 1.2 as a default in Windows 7. Refer to the Microsoft website for more information. Alternately, you can uninstall and then reinstall the latest version of OfficeConnect.
