Upgrade the Excel Add-in

The Add-in can be upgraded directly, without uninstalling the previous version first. To avoid compatibility issues, the installed Add-in version should always match the SEI Server version.

Upgrade using the installer

1. Close all open instances of Microsoft Excel.
2. Run the new Nectari/SEI Excel Add-in installer directly.
3. (Optional) Monitor installation or troubleshoot using log files if needed.

Version 2023 Release 2 or earlier

Upgrading from these versions requires uninstalling the previous Excel Add-in from each workstation first, then installing the new version using Nectari Excel Add-in – x64.exe (or SEI).
