Alan, I'm also trying to script the installer (unattended) for a build server. It's a Winforms solution and I currently have the following setup files: Infragistics_20182_Platform.exe, Infragistics_DevTools_20182.exe, and Infragistics_WinForms_20182.msi. Can you tell me which to use and what arguments (or point me to documentation)? So far, I've tried calling the Platform exe with /qn /key MYKEY /thirdparty /nofeedback. But that gives me an error related to DirectoryServices and complains about IIS Components and Visual Studio not being installed. I'd really like to just force the install to get it building.
