Hi Marius,
There are no plans to provide a custom directory chooser in MSI
installers produced by jpackage.
You can, however, customize it yourself. I assume you use WiX v3,
corresponding customization guidelines are available at [1]. Source code
of WiX v3 directory browser dialog - [2].

Hi all,
I was wondering if there are any plans (or if it is even possible) to
improve/modernize the directory chooser of a JPackaged MSI on Windows?
The current one looks pretty outdated and is also much harder to use
(compared to the modern file selection dialog).
I understand that this functionality is from the WiX Toolset. But I
still wonder if it possible to improve it / if there are any flags or
advanced UIs.
Also thankful for any tips or resources that are available, maybe this
can easily be achieved by overriding the default WiX template? I at
least found nothing helpful while researching (though that was some
months ago).
Thanks
