EventLogAnalyzer Agent - GPO Deployment

I'm trying to set up a GPO to automatically push the ELA agent, and there's a couple of old forum posts here about how to do it, neither of which have solid conclusive solutions.

The first option was to use the GPO to push the MSI file in the Computer Config --> Policies --> Software Deployment.

The second option was to use the msiexec.exe option as part of a logon or startup script to do the installation.

Since there's not much documentation in the help section about scripted agent deployments, and since I'm actively looking to get this set up as soon as I can, I wondered if I can get either some official response on how best to create a GPO to push the agent (and make it automatically show up in the console) or get other people's solutions to this.
