I have some experience to use Wsus Package Publisher. You do not need to install this application, just open the shortcut of application from unzip file.
Wsus Package Publisher is easy to control and use. I use Wsus Package Publisher
to deploy the non-microsoft such as adobe reader, adobe flash player, adobe reader font package, java, chrome and firefox browser for my organization. It work perfectly.
I also write some guideline for deploying firefox and java, Adobe Flash Player ActiveX with step by step with screenshots. I hope it can help you.
