New Post: Deployment of SAP network installer

I'm trying to publish a custom update using WPP to install SAP GUI using a networked installer.

My custom update is set to execute the exe setup file located on a publicly accessible network share and has some command line parameters set as well (one for targeting the proper update package from the SAP server, and one for making the installation silent). These are the same settings that work for this installation when executed directly on a machine.

The update fails through windows update, here is the excerpt from the log, does anyone have any suggestions for solving this issue?
