OK...I did what I should have done a couple tries ago...I added the logging switch to the msiexec command-line - looks like it is the Powershell Execution policy! Looks like the installer kicks off an Powershell script that is un-signed. In a corp environment where we have our PowerShell policy set 'safe' and only allowing signed code - this is going to be an issue.
