Ok /qb was not the issue but in doing it I decided to use the msi command build (wizard) utility to create the /qb switch instead of hand entering it. When I did this it created the command:
msiexec.exe /i "endpoint\Symantec AntiVirus.msi" /qb
So that gave me and idea change the default command that was automatically created when I created the package.
msiexec.exe /i "endpoint\Symantec AntiVirus.msi" /qn
Install is running now and not stopping on the 1619 error anymore!
