Dynamic Version Script for Slide Agent

I’m trying to get the version of the Slide Agent for a dynamic version script, but the only reliable place to retrieve it seems to be the file version or product version of the EXE installer available at a publicly available URL. The default Get-DynamicVersionFromInstallerURL returns 0.0.0.1 instead of the actual version shown when you right-click the installer and choose “Properties”. Any insight?
