How to show a language selection dialog

This task is very easy to accomplish. Please follow the next steps:

1. Now go to Builds page, Configuration tab and make sure the package type is set with .EXE output.
2. Go to Translations page and select the desired languages for the package
3. In the same page from the "Options" section, select the "Create only a multi-language package" radio button
4. In the same page from the "UI Language" section, select the "Display language selection dialog (for multi-language packages)" radio button

After applying the above settings, save and build your project. When you run the .EXE built with Advanced Installer, you will first be prompted with the selection dialog and then continue with the .MSI dialogs in the selected language.
