[wix-users] custom bootstrapper - customize UI .NET prerequisite installation

[Baumann Ingo]

I have implemented a custom bootstrapper application. Installing .NET Framework works fine as below.

<BootstrapperApplicationRef Id="ManagedBootstrapperApplicationHost">
  ...
  <Payload Name="redist\NDP452-KB2901907-x86-x64-AllOS-ENU.exe" SourceFile="sources\NDP452-KB2901907-x86-x64-AllOS-ENU.exe"/>
</BootstrapperApplicationRef>

<Chain>
    <PackageGroupRef Id="NetFx45Redist" />
    ...
</Chain>

As long as .NET Framework isn't installed, custom UI (WPF) can't be displayed.


1.       Is there any way to customize bootstrapper UI for installation of prerequisite .NET Framework when using custom bootstrapper?

2.       Although InstallCommand of NetFx45Redist (NetFX4.5.wxs) contains "/q", it's not installing silent. Is it possible to trigger silent installation of .NET Framework and display splash screen until custom bootstrapper UI is loaded?



Thanks
Ingo
