Software Deployment

I am trying to do a silent uninstall for the Jade Plug-In. They only provided a*.exe file and I was able to create a response file for the silent install. However, I have tried everything to do a silent uninstall. I used the uninstall string from the registry:

RunDll32 C:\PROGRA~1\COMMON~1\INSTAL~1\engine\6\INTEL3~1\Ctor.dll,LaunchSetup "C:\Program Files\InstallShield Installation Information\{C6F1EB49-E6B9-467A-BC3E-B74E2E17213F}\Setup.exe" -uninst

I've even shortened it to: "C:\Program Files\InstallShield Installation Information\{C6F1EB49-E6B9-467A-BC3E-B74E2E17213F}\Setup.exe" -uninst

It uninstalls; but not silently. And it doesn't respond to any switches. I have even used the -r switch to try and record the uninstall, but it doesn't work.

I also tried "C:\Program Files\Common Files\InstallShield\Driver\9\Intel 32\IDriver2.exe" /M{C6F1EB49-E6B9-467A-BC3E-B74E2E17213F} /uninst

Anyone have any ideas for me?

Thanks
