Choosing language manually in multi-language WiX installer

Question

I would like to build a multi-language installer for my App which is currently available in English and German. I will make the English Installer default and use a transform for the German Installer.

Instead of the Regional Settings automatically deciding the language of the installer, would it be possible to have a dialog box with the option to select the language?

Eg: As user in Switzerland, even though his regional settings are German should be able to install the English App without changing his regional settings.

Answer 1

You'll need to create a custom executable to run before the MSI executes to select the appropriate language transform to apply.
