Your BA (the custom Dll you create that burn calls) gets called before the chain executes. Your BA is the one that kicks off installation, uninstall, etc so you're in control. I think you can monitor what package is/will be installed and then decide what to display. I can't be more specific as I haven't used a custom BA. I use the standard BA (wixstba).

Subject: [wix-users] Fwd: Install WiX Bootstrapper Prerequisite Before Displaying UI
Is it possible to have one or more prerequisites installed before the Burn custom user interface? The scenario I have in mind is that the custom user interface depends on the prerequisites.
The documentation I have found thus far indicates that you use the Chain element to install multiple packages. The packages are installed in the order that they are listed in the Chain element. However none of the documentation I have found indicates at which point when the UI is actually displayed or how to control this?
One document on How To: Install the .NET Framework Using Burn <http://wixtoolset.org/documentation/manual/v3/howtos/redistributables_and_install_checks/install_dotnet.html>
seems to suggest that this may not be possible. For example it contains the following sentences.
"Target your bootstrapper application to the version of .NET built into the operating system. For Windows 7, this is .NET 3.5."
Why would it specifically state that you need to target the version of .NET built into the operating system if you could be certain that the version of .NET you included in the bootstrapper would be available at the time the UI is displayed?
