Excel Add-in Silent Installation

Install, update, or uninstall the SEI Excel Add-in silently, without any user interaction. This method is for IT administrators who need to deploy or update the Add-in across many workstations, or for automated rollouts and upgrades.

Use the -s flag to run the installer in silent mode (no user prompts will appear). The installer creates a log file (InstallLog.log for installs, UninstallLog.log for uninstalls) in the current directory, making it easy to review installation details and troubleshoot issues.

Always use an installer version that matches SEI to prevent errors and ensure full compatibility.
