Software Deployment

Hey All,

I am trying to install some software from Epson. Its a package that includes the following: 

• Scanner Driver and Epson Scan 2 Utility v6.5.20.0
• Document Capture Pro v3.0.0
• ISIS Scanner Driver v1.6.11706.12001
• EPSON Scan OCR Component v3.0.4
• Epson Software Updater v4.5.1

Inno setup package is what is used to package it. I tried using the following switches /verysilent /supressmsgboxes /norestart /sp-

Unfortunately I still get me prompt that says "This file contains everything you need to use your Epson DS-530. Click OK to continue.

Has anyone tried to silently install this package before? Not sure why the prompt still shows even if I'm using the /supressmsgboxes switch.
