Completely Silent Install of PrintShop Mail Suite 7

Using /s with PrintShop Mail Suite 7 installs silently except there is a Confirm message asking for confirmation to check for available upgrades.
Is there a command line switch, registry entry, or file that will disable this message?message

The installation has to be completely silent as it is executed through SCCM.
Tried using the .msi but the log files shows that it installed successfully but nothing was installed.
