Help deploying Authentication Agent using GPO

I have searched the forums (and Google) and I see where people talk about how they deployed SAA (or AAA) but no one describes how they did it.  I have tried writing batches to silently install the EXE or MSI and call those batches in a GPO but it either never runs or runs in the background and just sits (I can see the SAA installer icon and installer app name in running processes using 0% CPU, my guess it its hanging at the "Do you want to install this cert" screen).  I have also tried adding a Software Installation under Computer Config>Policies>Software Settings>Software Installation and it also never installs.  I have tried to run the file through a batch over the network and I also had the batch copy it locally before running it and neither of those made a difference.  I could not find any write ups that go into detail about the SAA in the knowledge base.  I made sure to run GPUpdate /force and restart the server to make sure the policies are being applied.  I have other GPO's and scripts running just fine.

GP Path: Computer Configuration>Policies>Windows Settings>Scripts

Here are the scripts I have tried that do not work for me:
msiexec /i "PATH\SAA_setup.msi" /quiet
msiexec /i "PATH\SAA_setup.msi" /qn
"PATH\SAA_setup.exe" /s
"PATH\SAA_setup.exe" /S
"PATH\SAA_setup.exe" /silent
"PATH\SAA_setup.exe" -s

I am just wanting to silently deploy and install Sophos Authentication Client for a domain (Authenticated Users).  Any help is appreciated.
